This is hands down the number one tire pressure gauge on the market for both go kart and car racers!

Now with the Prisma Electronics App, you can wirelessly connect your instruments to view and export all stored sessions! With the built in stopwatch, accurately check and save your tire pressures and time four of your competitors all in one device.

Keep track of both hot and cold tire pressures for multiple sessions as well as lap times for four drivers with 9 individual split times!

PRESSURE SHOT® FUNCTION

By activating the PRESSURE SHOT function through the menu, the tool stores the tire pressures when HOT without having to press any buttons. This feature allows you to save the pressures immediately, preventing the tires from cooling and obtaining unrealistic values.

Pressure Accuracy CLASS: 0.1%

Maximum error at 5 BAR: +/- 0.005 BAR — (0.072 PSI)
Maximum error at 1 BAR: +/- 0.001 BAR — (0.014 PSI)

Calibration

The Prisma 5 (HPM5X) digital gauge does not require calibration. The internal microprocessor calibrates the tool every time it is turned on to ensure correct readings at 100%.

Pressure and Temperature

Pressure measurement units in BAR and PSI
Temperature measurement units in CELSIUS and FAHRENHEIT

Set the direction of saving data depending on the circuit

Clockwise
