Frequently Asked Questions

What is the Prisma HPM5?

The Prisma HPM5 is a fifth-generation professional digital tyre pressure gauge designed for motorsport. It offers 0.001 BAR / 0.01 PSI resolution, wireless app connectivity, and advanced operating modes including Pit-Stop and P/T functions used in MotoGP, Superbike, GT Endurance, karting, and circuit racing.

Does the HPM5 measure tyre temperature?

The base HPM5 measures pressure only. To add temperature measurement, choose the HPM5 + Needle Pyrometer, HPM5 + IR Pyrometer, or HPM5 + Dual Pyrometer variants.

What is the Pressure OFFSET function?

The Pressure OFFSET function lets you set a hidden offset value so the display shows a different number to the actual pressure. This is used in the pit lane or on the grid to keep your exact tyre pressures confidential from competitors.

Does the HPM5 connect to an app?

Yes. The HPM5 connects wirelessly to the Prisma Electronics app (iOS and Android), allowing you to download session data, export to Excel or PDF, share with team members via cloud, and configure the instrument remotely.

What is the difference between the HPM5 and HPM4?

The HPM5 is the fifth-generation model with wireless app connectivity, improved operating modes, and a new aluminium tyre chuck. The HPM4 is the previous generation — still accurate and reliable, and a popular choice for karting and club motorsport at a lower price point.

Is this gauge suitable for karting?

Yes. The HPM5 is used across karting, circuit racing, rally, and professional championships. Its 0.001 BAR resolution makes it suitable for any category where precise tyre pressure management is critical.

Does Harris Race Radios stock this in NZ?

Yes — we are the Official NZ Dealer for Prisma Electronics and hold NZ stock for fast local dispatch.
