Mastercool’s Digital Thermometer/Hygrometer with Bluetooth® wireless technology works with our Mastercool Connect app to remotely provide dry bulb temperature, wet bulb temperature and relative humidity. Integrated into this unit is a high-performance ceramic antenna which offers maximum Bluetooth® wireless technology range. This digital thermometer/hygrometer will allow for varying the refrigerant charge in a system and seeing in real time how the supply parameters change, it will also do the same for vehicles.
The convenient clip, can easily be attached to a vent louver or register to see results more accurately. The mode key switches between dry bulb, wet bulb and relative humidity while the ˚C/˚F key toggles between fahrenheit and celcius for easy to read calculations.
