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

Great product, easy to use

Probe works great, but issue is using with app and smartphone, manifold. Used alone with app, shows temp and hum. well. If manifold pressure is used, it reverts to temperature only readout. . Reason why 1 star taken off. Also no instructions on tip , to twist open ! I almost tried pulling the tips off until my eye caught the groove part.

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.

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

Great item, I have others by Testo

Nice

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

Very accurate

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.

Does not integrate with the new Testo Bluetooth gauges. Has to used a stand-alone app on your phone. Poor range as well.
