AAB ABM-200 Airflow and Environmental Bluetooth Meter for Smart Phones, Black

I only tried it a couple times. I did order this model but received a black model called a CPS brand. Not sure why. It does work well but I only played around with it in my own home so far. Never took it to a job yet. Gave it 5 stars because I assume its the same and it worked so far. I like to give Amazon 2 stars for sending something different

I had an older plug in version that finally failed. Love the new Bluetooth design and is much easier to use now. I have sold a few jobs because the customer was able to see right away that i wasn't telling them a bunch of BS about their airflow being way to low and the cause of their issues. Its fairly accurate to and sure beats the hell out of breaking out the belometer. You can put in your K factor for tighter accuracy. It can total up the cfm of all of your registers and be able to email it to you client with a professional look. I don't think the NEBB certified would get caught dead using one but it does exactly what i need.

This is really very helpful and easy to use; especially, around the house. Because I can record the air flow and other information and I can check it regularly without a lot of hassle, it can indicate if I am starting to experience problems so I can fix them before they are bigger problems. One thing that can save a bunch of money is it will indicate when your filter is really ready to be changed early or later then the specified date.

I returned this item fairly quickly after getting it. The thermometer portion of this should work well, but when I tried getting it to read the ambient temperature, it wouldn't. I put it in the fridge for over an hour and it had only dropped to a temperature of 65 or something like that. If it couldn't read the temperature correctly, how could I rely on it to read the pressure, airflow, etc. So I returned it.

WOW! If you are a DIY kind of person this meter is for you. I have a 4,000 sq ft home with only a single 5-ton unit. My house is 10-yrs old and I have never been able to get "total" comfort even from day one. Crazy to live 10-yrs like that huh? It has only been the past 4-yr where brain/body has been sober enough;-) Anyway I had been looking at a "zoning" system. After all damper and controllers I was looking at almost $3000. I balance airflow and pressure for around $130! I will say I used the counterpart kit which is the AAB SPM-K1 which handles the static pressure portion. I do wish wish there was better training/documentation center on the site, but overall this product is very intuitive. Some simple physic and math (and Google) will get you there easily!

This meter takes all the guesswork out of troubleshooting and balancing a Central Air HVAC system. The iPhone software does some things that don't make sense, but the basic data is all there. I did not use their CFM calculations, because they just use approximations for register restrictions. However, the air Velocity, drybulb and wetbulb Temperature, and Humidity measurements are invaluable. Combine the output data with a few spreadsheet calculations to get a comprehensive understanding of your HVAC airflows.

As a home inspector, I use this tool to verify airflow at the HVAC registers. It works great. This tool can be used by HVAC professionals to calculate airflow when performing balance testing.

Doesn’t connect have the time using blue tooth. I am a licensed HVAC contractor and was looking for a small airflow instrument. I called and wrote company and they do not return calls or email.

Works very well now that the app updated.
