Digital Tire Pressure Gauge with Dual Pyrometer
Digital tire pressure gauge with dual pyrometer

This new product version joins Prisma Electronics tire pressure gauge HPM4 with an infrared Sensor (PYR2-IR) and a K-Type Thermocouple probe for having a complete solution to measure tire pressure and tire temperature in the racing application.

The infrared sensor is ideal for the tire surface temperature measurement thanks to its fast response time (0.1 sec) while the K-Type thermocouple probe is ideal to measure tires’ compound temperature at specific points.

This digital tire pressure gauge with dual pyrometer has been engineered for the tire specialist who wants to know exactly how to optimize racing tires’ performance.

With our digital tire pressure gauge with dual pyrometer, you have a complete and unique tool for measuring tire pressure and temperature with high accuracy and precision.

Dual technology for tire temperature

You can choose whether to measure the temperature of air, asphalt, and tires with the needle probe or with the infrared sensor.

The device memory has a capacity of 50 sessions – Pressures + Temperatures

The digital tire pressure gauge with dual pyrometer engineered for tire specialists


It is useful to have in the same device a thermocouple probe to measure the tire compound temperature at specific points and an infrared sensor to measure the tire surface and average temperature. This is the reason why we have engineered this device with Dual Technology.

It is possible to set the Infrared Sensor or Thermocouple Probe to measure the tire compound temperature.

Infrared Sensor

With our digital tire pressure gauge with dual pyrometer, you can quickly measure the tire surface temperature with a time response of 0.1 sec. Using the features of the FOV (35°) you can measure the average tire temperature while, for more info about the tire temperature, you can also utilize the IR sensor.

K-Type Thermocouple Probe

With the k-type thermocouple probe, it is possible to measure the compound temperature at three different points (EXTERNAL – INTERMEDIATE – INTERNAL) to understand the dynamic setup of the vehicle. For example, if you have a BLISTERING or GRAINING effect, it is possible to measure the tire compound temperature at these points.
