The system can monitor tyre pressure from as low as 10 PSI, which is perfect for 4WDers. It can monitor up to 75 PSI, which is also appealing to some drivers of maxi taxis, cars, motorhomes and mini buses etc.

The system monitors both pressure and temperature, and will alert the driver of leaks, punctures or over-heating (over 80 °C/176°F) and low battery etc. In addition, the alarm threshold of pressure can be set and adjusted by the driver.
