Greater than one weekIf 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.

> 3 dayOf you arent taking delta T on both wet and dry bulb temps your missing a big part of what the HVAC-R system is doing. This doesnt have the greatest range but both that has to do a lot with building materials between you and the probes. They are accurate and precise because they almost match each other. Great for diagnostics and for quickly giving value added to preventative maintenances.

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

12-06-2025Probe 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.
