Our new TPMS-IR21 sensor which boasts five key areas for tyre analysis. High precision pressure, rim temperature via contact patch, internal temperature, relative humidity and inner liner temperature measurements. Carcass temperature is measured with a 5 channel infrared system with 14 point calibrated array. Any 5 of those 14 points can be selected using the handheld receiver. The rim temperature feature is also unique as it provides a true rim temperature measurement via contact patch, so not just the sensors internal temperature like most available systems.
