Low pressure test

The receiver will continuously beep and flash when low pressure is detected.

 

Final thoughts
The 70mai TPMS Lite is very nicely built. Each sensor has laser-etched markings with QR code for longer durability.

The only drawback that the pressure is measured in Bar only. I wish there is a setting to can change to use Pounds per Square Inch (Psi) also.

Luckily here we are also using Kilopascal (kPa). Conversion from Bar to kPa is 1.1 bar is 110 kPa.
