Features: 1. tire preure and temperature monitors and screensIn real time.2. It controls the voltage of the sensor batteries.3. Activate audible and visual alarms: low preure,High preure, high temperature, fast leak, low sensor batteryAnd there is no sensor signal.4. shows the preure in kPa, Bar, PSI5. Show the temperature in 6. allows to set thresholds for low preure and high preureAlarms7. Supports sensor pairing and sensor position exchange procedureTo facilitate the rotation of the tires.Work environmentReceiverWorking temperature: -20 ~ 70 Storage temperature: -20 ~ 80 Working voltage: 12 VTPMS sensor:Working temperature: -400 ~ 125 (internal sensor) / -20 ~ 85 (external sensor)Storage temperature: -400 ~ 125 (internal sensor) / -20 ~ 105 (external sensor)
