With over approximately 60% of cars on the road running with incorrectly-inflated tyres, TPMS systems (Tyre Pressure Monitoring Systems) are recognised as a vital safety aid to help prevent issues with tyre under-inflation and the accident risk / increased running costs associated with it. This tyre Pressure Checker is used in conjunction with the excellent Fit2Go Tyre Pressure Monitoring System. Simply hold the checker close to the Fit2Go Tyre Pressure Sensor on the tyre valve to receive an instadnt reading of tyre pressure and sensor battery life. Extremely small and portable, the Pressure Checker can be kept in a pocket for instant use if required. As with other Fit2Go items, the Pressure Checker integrates easily into the system with no extra programming or coding required.
