HPM 4X digital tire pressure gauge with needle tire probe pyrometer

Managing racing tires is a complex task that requires a deep understanding of the ideal tire temperature and pressure.

Good race teams understand that small changes in these parameters can have a significant impact on the balance and performance of their car or bike.

Racing tires have a narrow operating range, and operating outside of this range can lead to decreased performance and increased tire wear.

To effectively manage your tires, you need accurate measurement tools such as a tire pressure gauge and pyrometer.

Our digital tire pressure gauge with pyrometer and needle probe allows you to easily measure and save all of your tire parameters in one device.

K-type thermocouple needle probe included

Thanks to the high accuracy of this K-type thermocouple needle probe included with this Prisma Electronics digital tire pressure gauge, you can measure and save tires’ compound temperature at three different levels: EXTERNAL – INTERMEDIATE – INTERNAL.

Digital tire pressure gauge with tire pyrometer: your best partner for measuring racing tires pressure and temperature

Useful when you want to understand the effect of the CAMBER and CASTER in cars and also the temperatures in the different lean angles of the bikes.

It is possible to evaluate the dynamic setup of the vehicle through the evaluation of temperatures in all the different points of the tires.

Vehicle setting
Through the Menu, it is possible to set the vehicle – AUTO (4 wheels) – MOTO (2 wheels)


By activating the function in digital pressure gauge mode, the instrument automatically stores the hot pressures of the current session without pressing any buttons.  

PRESSURE and TEMPERATURE measurement units
  • BAR and PSI for pressure
  • CELSIUS and FAHRENHEIT for temperature
Pressure measurement accuracy: 0.1%
  • Maximum error at 5 BAR: +/- 0.005 BAR — (0.072 PSI)
  • Maximum error at 1 BAR: +/- 0.001 BAR — (0.014 PSI)
Tire temperature RESOLUTION
  • 0.1 °C / F  Temperature resolution
  • Temperature error : +/- 0.2°C


The HPM4X digital pressure gauge does not require calibration. At each startup, the internal microprocessor calibrates the sensor to provide a reliable measurement of 100%.
