Testo 605i | Thermohygrometer for Indoor Temperature and Humidity Measurement | with Bluetooth Support

Great tool to add to your toolbox if your a HVAC tech.

If you want to set this unit up somewhere that is not easily accessible and walk out of Bluetooth range the Bluetooth shuts off after 10-15 minutes or so. So then you have to climb back up to where ever to restart the Bluetooth so you can reconnect to it. I was going to buy more of these tools but they all probably have this issue. There should be a way to disable auto shutoff.

Great product, easy to use

If you have an older phone or a phone that hasnt been updated to the newest android or ios then this tool will work great. However, if you have a newer phone, particularly a samsung, then check the reviews on the play store. The app is nearly unusable on newer phones. Several features dont work properly and it is extremely buggy.

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.

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.

Bought this tool for my boyfriend who’s a HVAC tech. App is clean and easy to use. He was very pleased.

Nice

Very accurate

Works perfect with my testo 550i connectivity is spot on with Bluetooth
