Turn on and throw it inside of a refrigerator you’re temping down and checking cut in cut out temps on and don’t have to worry about opening the door to check on it just download the app and see everything on your phone. Bluetooth distance is further then I thought it’d go. Also batteries last pretty long as well

I wanted something I could use as an easy humidity standard. This unit had the best specs for the price. I bought it despite the drawback that it had no visible meter and needed a smartphone to display the readings.Turns out the smartphone requirement was its best feature. It will display a real time graph of the temperature and humidity readings. You can use the graph to see when it stabilizes, plus it will show you the fluctuations in the humidity and temperature.Since I'm using it for a humidity standard, couldn't calibrate that. I did calibrate the temperature readings against a lab thermometer. They exceeded the claimed accuracy. The difference between the readings of this instrument and the lab thermometer were essentially nil.

Fantastic probes with clear readings on the app. Grabbed two and my TD was always spot on. Discovered low charges more accurately than a thermometer.

Product is good, no issues. However, do your research on Testo and their warranty. Who or where you buy from may have a significant impact.

Helps when tracking temperature and humidity in many applications. I use it to check the temperature inside WI coolers during unit startup. This probe along with the pressure and temperature sensors allow for TEV adjustment and monitoring out side the cooler in most cases. You can also use it to determine the correct charging of AC systems using piston type metering devices to determine wet bulb temperature of the space. I’ve just loaded the new testo App but the older one worked well for me.

It seems to be reasonably accurate. I have no means of verifying calibration. However, it is serving the purpose of measuring temperature and humidity across floors and rooms in my home very well. It confirmed my suspicion that my home thermostat is over reporting the temperature and under reporting humidity levels, and that I have significant variation of both thru my home.
