TPMS constantly monitors tyre pressure and tyre temperature and alerts the driver when the tyre pressures or temperatures are abnormal by changing the display from Green to Red and by an audible alert.
This system measures pressures from 40psi to 105psi. The system operates at 24V. If this unit is being installed on a vehicle with a 12V supply, the system will need a 12V to 24V converter to operate.
