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 that 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 a dry bulb, wet bulb, and relative humidity while the ° C/° F key toggles between Fahrenheit and Celcius for easy to read calculations.
