pH EC PPM Monitor for Hydroponics Growing System, Continuous Monitoring TDS Conductivity Temperature of Hydro Nutrient Reservoir Tanks Indoor Vertical Farm DWC Aeroponic Garden for Home Growers

I used this water monitor for my last hydroponic cannabis grow and it performed well. I did have an issue with the probe not calibrating, but once I contacted customer service, they sent me a new unit. There is no such thing as a perfect meter, but at least you know you can depend on this company to help when something goes wrong. To improve the accuracy and performance, it is important to clean the probe and re-calibrate it often. I did this every time I did a rez swap (once a week or once every two weeks) and the meter worked great! I love that it is WiFi and I can see what is going on in my grow room without having to be in my grow room. There are more expensive units on the market, but if you read the reviews, they have the same issues. Spend less!

Of course it failed at the worst possible time. Was easy to setup and use, the app is nice but the probe and unit are bad or will go bad in a short time. It is cheaply made. Wish it were better but units that work properly in this segment cost more. Guess I am ponying up to buy more expensive. Sure wish I didn't waste money on this first! So, you have been warned. At least you got notice I didn't have. This will fail within a few months, if you choose this path, get a backup. And Good Luck if you think contacting the company will help.

I recently purchased the YINMIK pH EC PPM Monitor for my hydroponics growing system, and it has proven to be an invaluable tool for maintaining the health and productivity of my plants. This monitor has made continuous monitoring of pH, EC, and PPM levels incredibly convenient and precise, and I'm excited to share my positive review.First and foremost, the YINMIK pH EC PPM Monitor is exceptionally easy to use. The setup process was straightforward, and the provided instructions were clear and helpful. I had it up and running in no time, and it immediately began providing accurate data about the conditions in my hydroponic system.The continuous monitoring capability is a game-changer for hydroponic growers. Instead of periodically testing and adjusting pH, EC, and PPM levels, this monitor does the work for you in real-time. It provides a constant stream of data, allowing me to make timely adjustments to ensure optimal growing conditions.The accuracy of the readings is impressive. I trust the data provided by this monitor, which is crucial for making informed decisions about nutrient dosing and pH adjustments. It has significantly improved the precision of my hydroponic system management.The convenience of having all three monitoring functions (pH, EC, and PPM) in one device is a significant advantage. It eliminates the need for multiple meters and simplifies the monitoring process. The large, easy-to-read display makes it simple to check the readings at a glance.The YINMIK monitor is durably built and feels robust in hand. It's designed to withstand the rigors of a hydroponic environment, including exposure to moisture and nutrient solutions. This durability gives me confidence that the monitor will last for a long time.The included calibration solutions and carrying case are thoughtful additions. They ensure that I have everything I need to maintain the accuracy of the monitor and keep it protected when not in use.In conclusion, the YINMIK pH EC PPM Monitor for Hydroponics Growing System is an essential tool for any hydroponic enthusiast or professional grower. Its ease of use, continuous monitoring capability, accuracy, and durability make it a standout choice for managing and optimizing hydroponic systems. I highly recommend this monitor to anyone looking to achieve precise control over pH, EC, and PPM levels in their hydroponic setup. It's a valuable asset for promoting healthy and productive plant growth.

I have a hydroponics tub I use this with. I also own Blue Labs pH and EC measuring tools. The YINMIK monitor matches the same readings as my Blue Labs pens initially but falls off quickly. This monitor is convenient and has a lot of readings. I did NOT download the app so I am happy that this monitor works great without needing to get the app and did not require the app to function.The accuracy of the probe seems to have already started falling off after a week for both the pH and EC compared to the readings of my blue labs pens. They are still close though but off by a few tenths. I like how it comes with calibration liquid for pH but unfortunately it does not come with any calibration for the EC. I wish it did instead of having buyers just trust that calibration from factory is accurate. I had to get a new one of these monitors because the first one they sent, the power supply was faulty. Wish it had a screen dim feature when not actively in use but it does not so glows green constantly.

Dead on arrival, measures PH inaccurately, no PPM readout stays at 0Most expensive temp monitor I’ve ever purchased

Seems to work well, clean regularly and calibrate about every two weeks.Probe, cable & connector are sturdy. The lighted display is so nice, especially at night.For the money, should have a little better-stronger (stainless) hangers(s)-not one in the middle, but two on either side. The cables make it hang unlevel.This is my first monitor like this, overall glad with the purchase.

I purchased there meter and was having problems with its read out. Showed pictures to the customer support team and they said it was probably the bulb. I explained that I live on a boat growing food hydroponicly and we are setting for passage in 5 days. Rather than send me just the bulb they sent me a whole new meter because it could be shipped overnight. What a surprise to find a company that actually cares about its customers and there issues. Didn’t think there were any left.New meter is working great. Highly recommend this meter. Tells you all you need to know with one dip of the wand in the nutrient solution. I still have my cheap pencil testers A’s back up but don’t think I’ll ever need them. Kit comes w ph buffer solutions, not powder. Much better.
