AcuRite Digital Wireless Fridge and Freezer Thermometer with Alarm and Max/Min Temperature for Home,LCD Display, Restaurants (00986M), 0.6, White

I am so pleased with this thermometer and its sensors. I purchased it because the freezer failed on my 7 year old refrigerator, and I didn't know until it was too late to save the food in it. So several hundred dollars later, I am up and running again, but this isn't going to happen a second time! I found that setting everything up was a breeze - except the thermometer readout kept saying 71 degrees in the refrigerator and 70 in the freezer - it wasn't even that warm in my house! So I emailed the company, and never received a response - nice! But finally a light bulb went on in my head and I hit the "reset" button on the monitor - and then it started working just fine. You do need to use lithium batteries in the freezer sensor for the best performance. And I found that the suction cups simply don't work for more than a minute or two, so each sensor is clipped in place, which is not a problem, since the sensors come with built-in clips. As far as accuracy, I have no way to test, but it does show very satisfactory readings in both refrigerator (39 degrees) and freezer (3 degrees), on the Power Saver mode. That works for me. I think the thing I like the most about this monitor is that you can tell what the temperature is inside the unit WITHOUT opening the door - before I had one of those cheap dial thermometers that hung on the freezer shelf, and you had to open the door and really squint at it to see how cold it was in there (or not, for awhile, until the repair guy got here!). Well, I have learned my lesson and I consider the money I spent for this monitor to be an investment in making sure my refrigerator and freezer are running correctly and that the food is safe to eat! I almost forgot - each sensor has a "minimum" and "maximum" temp setting so you can see if any temperature variations have taken place recently. And there is an alarm for each sensor that will go off if the unit gets above your preferred setting for 15 minutes, but I have not yet set them up - I'm still cleaning up after the freezer disaster! Even if you're not having trouble with your refrigerator and/or freezer right now, you should get this monitor, because - believe me - someday you WILL, whether it's a power outage, or a fan goes out, or whatever. At least with this you'll have an early warning system before your food goes bad. I've been there for the past week, and you do NOT want to go there - it is very, very expensive!

I'll preface this by saying I bought this b/c my relatively new fridge seems to hold temperature poorly, so I've had a small mercury type fridge/freezer thermometer (hereafter referred to as "Mercury") since shortly after I bought it. The problem with these is that you have to open the door to read it, and I wanted something that I could have a Min/Max reading throughout the day to note down in case I need ammunition to use against the warranty company. Being able to monitor both fridge and freezer temps is a big plus! BOTTOM LINE: for those not wanting to read my drivel below -- The AcuRite 00986, after a week of use, works great for me... note that I had no battery issues like some have had. See next part... BATTERY TIPS: doing a Google search on battery characteristics, I found information [link removed by Amazon...] on Alkaline versus NiMH versus NiCd versus other battery chemistries. One of the very useful pieces of info was operating temperature range. Of note: Lithium operates down to -40C (-40F). Alkaline: 0C (32F). NiCd: -40C. NiMH: -20C (-4F). Well, I have a zillion NiMH rechargeable batteries for kids toys and since I really only care if the freezer goes above a few degrees F, then I figured I'd try NiMH for my sensors, before shelling out $$ on the Lithium AAs. Results: my freezer sensor has captured a temp as low as -13F, so I'd say the NiMH option was a smart move. Even if I have to change the batteries weekly, I swap them out with another set of NiMH and put them on the charger for a few hours. So, my advice to you is to get an inexpensive NiMH charger from somewhere ($10 maybe) and a package of at least 4 (~$7-10), but 8 would be nice, NiMH batteries. I'd recommend any low-discharge NiMH, such as Sanyo Enloops. If you really want to cheap out, get NiCd, but they don't have the capacity that the NiMH batteries do. I know the investment is a tad high upfront, but one set of Lithium AAs is $6, and it's single use. With the NiMH, you can use them hundreds of times, and with 2 each in your fridge/freezer sensors, the back-up ones could be in your kids RC car, flashlight, etc. You'll save $$$$$$ in the long run, if you switch your household to rechargeable in general for AAA/AA type applications. Ok, all the important stuff over, here is the boring, wordy review/information: I received the AcuRite version (I'm guessing the Chaney branding has gone extinct) of this product, opened it, installed batteries (more about the batteries later), and within seconds, the transmitters were sending temperature information. I let it sit on my desk for a while, and after the sensors stabilized, they were within 1 degree Fahrenheit of each other, and right at what my home thermostat was set to. Good so far! I then moved to the kitchen and put the sensors in the fridge/freezer, and mounted the display on the side of the fridge next to the freezer. It probably took between 10 and 15 minutes for the sensors to stabilize at the fridge/freezer temps. I bought another mechanical dial type thermometer (Taylor Classic #5924) from Amazon so I could compare the results with the AcuRite and Mercury. I started my "analysis of performance" by placing AcuRite #2 and Taylor in the freezer, and AcuRite #1 and the Mercury in the fridge. They all seemed to line up well, and I monitored things this way periodically over the course of the next few hours. Because my fridge is my biggest worry, I then moved Taylor to the fridge as well, and placed it somewhere else in the fridge away from AcuRite #1 on a different shelf. This way I could tell if temps across fridge were consistent. Again, everything seemed to read similar temperatures, so I'm confident the AcuRite system is A-OK for me.

I bought two of these because I wanted to monitor three areas: 1) the fridge compartment of my refrigerator, 2) the freezer compartment of my refrigerator, and 3) a deep freeze located in my kitchen about 15 feet from the fridge. I bought the first thermometer about 18 months ago and added the second unit a month ago. Here's what worked well: - The temps are accurate enough based on comparing with a couple of analog thermometers I have, with only a degree or two difference here and there. - The alerts are simple to set. - The alarms are loud enough. I can barely hear them upstairs in my bedroom, but I can hear them. If I'm awake, I can hear them anywhere in my house. Here's what did not work well: - There is a conflict between the two base stations and the four remote units. I've deployed both freezer remotes plus a single fridge remote. The freezer remotes each paired with their respective base stations, but the fridge remote paired with both. Not a bit deal to me--the fridge remote on my deep freezer base station is just a duplicate of the fridge remote. But if you have two fridges with freezers, you might wind up running into issues keeping the devices separate. The biggest issue I have is the alarm setting for my fridge's freezer. My freezer has a defrost cycle that heats up the freezer compartment to around 16 degrees for a very short time before rapidly cooling back to -10 degrees or so. My understanding is that this behavior is normal, and the food stored in my freezer will not be affected due it it's being frozen solid and the short duration above 0 degrees. But this of course means that I can't set my freezer remote alarm to the 0 degrees the FDA recommends as a minimum freezer temperature. The best that I can do to take advantage of the freezer alarm is to set it for 16-ish degrees in case my freezer completely fails. Overall, I'm happy with these thermometers. They have worked reliably so far. In fact, this alarm notified me last month that my freezer was too warm. Turned out the defrost wasn't working and the coils were iced up. I don't see any way around the daily temperature spike due to my freezer's defrost cycle, so I can't blame this device for not being able to tell if operation is normal or not. Actually, what would be great would be a freezer whose thermostat is tied in to the defrost process so it would know what acceptable temps are during normal operation and during defrost cycle. It could then send appropriate alarms.

As a former chef, I know how important it is to know how my freezer and refrigerator are working in real time. So easy to set up and use, and now I know what the real temps are, and that means my food is stored in optimal conditions. My ice cream is at the perfect temperature for serving and I never have frozen lettuce, yet my favorite beverages are very cold.

DO NOT WASTE YOUR TIME. I must admit that I had high hopes for this remote thermometer to work, as I am not keen on having a freezer problem and see all that food spoil. Speaking to customer service at Acu Rite (by the way, very courteous and attentive) confirmed that IT SHOULD WORK as set up. Sent us a replacement unit that also fails to record temperature inside the freezer/refrigerator. Fist unit would not show the temperature of either sending unit. Changed batteries, reset units with the Acu Rite customer on the line, recorded ambient temperature, but failed to send any update signal. Customer service at Acu Rite trouble shot the system and told me she would send a replacement. By the way, I had done the same reset procedure as Acu Rite at least 10 times during the first week of having the unit. It will reset and correctly read when the sending units and the receiver are side by side on my kitchen table. After placing the sending units in the freezer and refrigerator, the temperature showing on the receiver (from the reset with the customer service rep on the line) is the only thing that shows for days. I received a replacement unit from Acu Rite under warranty a couple of days ago and it behaves the same way. Bought a fresh set of expensive Lithium batteries for the sending units. Performed a reset a couple of times and the receiver still shows the temperature from the side-by-side reset. I am beginning to wonder if I have special freezer/refrigerator units that have special enclosures with special coatings that prevent these units from working. I tried to also leave the freezer/refrigerator door open for at least a couple of minutes and see if the 16-second cycle would trigger anything. Absolutely nothing. Same temperature showing from the reset 2 days ago. As if the sending units "freeze" when placed in the freezer/refrigerator. The red LED does not blink, not even once when in the refrigerator/freezer, but this may not necessarily be the expected result for the 16-second cycle. Acu-Rite customer service tells me that the LED should blink every 16 seconds. If you want to spend money on a digital display that WILL NOT tell you the current temperature in your freezer, then this is the unit to buy. I have gone back to a daily check on the old fashioned analog thermometer I placed inside the units. One last comment - Do you wonder why all reviews online with Acu-Rite are glowing top reviews? Because they will not post my review that is almost a replica of this one. I must only presume that the folks managing reviews at Acu-Rite remove all negative ratings. Amazon has over 240 ratings - Acu-Rite has 17.

UPDATE !/16/25: Still working great! But I just wanted to tell you that I bought a second unit for the bedrooms so we can check temps from the living room. You can't use a second set because it picks up the sensors in the fridge and freezer, even though I have batteries in the two new sending units which are I the bedrooms. So I have been using the monitor in the living room to keep an eye on the fridge temps. But now one of my friends has had a few power outages, so I'm going to give the second set to her. I am so glad I got this item. Now I can track the temp of my fridge and freezer without opening the doors! It was a simple matter of inserting batteries and placing the sensors in place. I have the monitor on the side of my fridge via the 4 magnets, but you could also hang it on a nail with the hole on the back. The sensors take 2 AA batteries each, and the monitor takes 2 AAA batteries. I used regular alkaline batteries (Duracell). I opted to not pay for expensive lithium batteries. So far, I have had no problems. I had a power outage in the recent past, and would have liked to know what the inside temps were in my fridge (without opening the doors), so I would know when to go get ice. The suction cups did not work, the sensor units fell within seconds of placement. I did not clean the wall prior to placement, so that could be a factor, but I would rather have them sit on the shelf anyway. On the back of the monitor, you have a switch for Celcius or Fahrenheit, as well as a reset switch. I do not use the alarms. You have to program the alarm settings if you want to use them. You can reset the hi and low reading by simply pushing the "clr" button. *** UPDATE 9-26-17 *** I had a 10 hours power outage about a month ago. This acurite unit performed FLAWLESSLY! I monitored the fridge and freezer temps constantly, and when the temps got too low, we went out and got bags of ice so we could put all the food in an ice chest. Then I put the sending unit in the middle of the ice chest to make sure the temp remained low enough. I can't love this item anymore than I do right now! Worth every penny in my book. NOTE: I still have the same batteries in it, and they are still going strong. I do not use the alarm. But I do check the high and low temps every morning and then reset, and I check and reset at bedtime. My freezer temp ranges from -5 degrees (f) to 10 depending on how much we open the door. It does not seem to affect my Duracell alkaline batteries. Very happy I did not pay for lithium batteries. UPDATE 8-27-18: This unit is still going strong! I recently replaced all original batteries (at about 8 months in), even though they were working just fine. I wanted to make sure the batteries did not die when I had a power outage. This is the best unit. UPDATE: 11-15-23 Still going strong! I can't tell you how many times this unit has helped during power outages. We don't turn the generator on until the fridge hits 40 degrees. We are constantly checking the temps day and night for piece of mind. I'm going to buy another set to measure for cold drafts in the bedroom. Two points of reference, one display. I'm amazed how many years we have had this, and it still works.

I bought this almost a year ago. Set it up and mostly forgot about it. At 3 a.m. this morning (why is it always 3 in the morning?!), I heard it beeping. The breaker that has been running my freezer for years had tripped. Without this sensor, I'd have a huge mess and be out all my frozen food. Every freezer should have one. Highly recommended!

I've had two of these for a few years now (originally got one for the kitchen fridge, then bought a second unit for the deep freezer.) The pluses and the minuses are below. First, the minuses: The first thing is that this is supposed to be able to stick to your fridge magnetically. But, they cheaped out on the magnets. The magnets in the back are NOT strong enough to hold this device onto the fridge. The motion of the door makes it fall off, and when not falling off, it is gradually sliding down. We added some heavy-duty magnets between it and the fridge to keep it on there. The second thing to know is that the freezer sensor on the first one I bought went bad, after less than 2 years of use. You can't buy replacement sensors, so I ended up buying a whole new unit. I hope that this is a fluke, and the current units last longer. I will update. The pluses: I have a temperamental refrigerator. It came with the house and it still runs so I would rather use it than replace it. But it's very responsive to changes in barometric pressure. Sudden cloudy or rainy days? The refrigerator temps drop and things freeze. An engineer friend explained it to me once but I don't really understand it, I just live with it. I like having the temperature display on the front of the fridge so that if there's a problem, I can see it right away. I also like that this device has a safety alarm if temps get too low or high. The device works for that. The batteries need replacement every 6 months or so.

Great product! I have a double door refrigertaor and a deep freezer. Makes me feel safe to be able to monitor the temperature in both. I actually turned down the freezing control to lowest setting in my deep freezer, when I realised that temperature was always showing as lower than -18 celsius. Also helped me realise that freezer in my samsung double door has very wide variation between -5 to -18 on daily basis. Made me realise that it would the reason why ice cream are kind of soft , in the freezer of my double door, compared to deep freezer. I guess that is the reason consumer product companies, don't put temperature displays on the common refrigerator.

Perfect... Item as described..quick delivery

Its very good peice .. and give you correct dgrees .. thank you
