Which Prisma HPM5 Tyre Pressure Gauge Is Best for Karting?
For kart racers, tyre pressure is one of the most important setup variables available. A change of just a few tenths of a PSI can dramatically affect grip, balance, and tyre wear. That's why many teams invest in high-precision tyre pressure gauges, and the Prisma Electronics HPM5 range has become a popular choice throughout the karting paddock.
But with six different models available, which one is right for your team?
This guide breaks down the entire Prisma HPM5 range.
Why Tyre Pressure Matters…
Unlike many forms of motorsport, karting has limited setup adjustments. Tyre pressure often becomes the quickest and most effective tuning tool available.
Accurate pressure management can help with:
- Improving grip levels
- Managing tyre temperatures
- Controlling tyre wear
- Adapting to changing track conditions
- Optimising performance throughout a race day
The HPM5 range is designed specifically for this level of precision, offering pressure readings down to 0.01 PSI.
What All HPM5 Models Have in Common
Every HPM5 model includes:
✅ Ultra-high pressure resolution (0.01 PSI)
✅ Wireless connectivity to the Prisma app to view all stored sessions
✅ Session data logging
✅ Pressure history tracking
✅ Cloud sharing
✅ PDF and Excel export
✅ Pressure offset functionality
✅ Pit-stop mode for rapid adjustments
For many kart teams, these shared features alone justify the investment.
1. HPM5 - HiPreMa5 – The Best Entry-Level Option
Ideal For:
- Club racers
- Owner-drivers
The HiPreMa5 is the simplest model in the range, focusing purely on pressure measurement.
If your primary goal is accurate pressure management without additional data collection, this is likely all you need.
Pros
- Lowest cost in the range
- Simple operation
- Same pressure accuracy as premium models
- App connectivity included
Cons
- No temperature measurement
- No stopwatch functionality
Verdict
For most club-level kart racers, the HiPreMa5 offers the best balance of performance and value.
2. HPM5 with Stopwatch – Best for Team & Endurance Karting
Ideal For:
- Multi-driver timing
- Teams wanting timing functionality
This model adds an integrated stopwatch while maintaining all of the pressure management features of the standard HiPreMa5.
Pros
- Built-in timing
- Great for pit lane operations
- Minimal price increase
Cons
- No temperature measurement
Verdict
The stopwatch feature can be a genuinely useful for multi driver timing combined with accurate pressure management.
3. HPM5 with Infrared Pyrometer
Ideal For:
- Intermediate racers
- Teams learning about tyre temperature
An infrared pyrometer allows surface temperatures to be measured without physically touching the tyre.
Pros
- Quick readings
- Easy to use
- Additional setup information
Cons
- Measures surface temperature only
- Less accurate than probe systems
Verdict
A useful step into tyre temperature analysis, although surface temperatures can change very quickly after a kart leaves the track.
4. HPM5 Infrared Pyrometer with Stopwatch
Ideal For:
- Advanced race teams
- Teams wanting an all-in-one solution
This combines infrared temperature measurement and stopwatch functionality into one unit.
Pros
- Complete feature set
- Convenient for race weekends
- Excellent data logging
Cons
- Still limited to surface temperature readings
Verdict
A strong choice for teams wanting maximum functionality without moving to a probe system.
5. HPM5 with Needle Probe Pyrometer
Ideal For:
- National-level competitors
- Serious tuners
- Data-focused teams
Needle probes measure temperature within the tyre tread rather than on the surface.
This provides significantly more useful information when assessing:
- Tyre loading
- Chassis balance
- Setup changes
- Tyre performance consistency
Pros
- More accurate temperature analysis
- Valuable setup information
- Popular with competitive teams
Cons
- Requires contact measurement
- Higher price
Verdict
For racers chasing tenths rather than seconds, this is where temperature analysis becomes truly valuable.

6. HPM5 Dual Technology Pyrometer
Ideal For:
- Professional kart teams
- Driver coaches
- Race engineers
This flagship model combines both infrared and needle-probe temperature measurement.
Pros
- Surface and internal tyre temperatures
- Maximum data collection capability
- Professional-grade analysis
Cons
- Highest purchase price
- More functionality than most club racers require
Verdict
The ultimate tool for professional race engineering and advanced setup work.

Most Kart Racers
HiPreMa5 or HPM5 with Stopwatch
The best combination of accuracy, simplicity, and value.
Adds useful timing functionality without significantly increasing cost.
Serious Competition
Needle Probe Pyrometer
Provides meaningful tire temperature data that can improve setup decisions.
Professional Teams
Dual Technology Pyrometer
The most complete solution available.
Final Thoughts
For the vast majority of kart racers, accurate pressure measurement is far more important than tyre temperature analysis. The HiPreMa5 and Stopwatch models deliver the same pressure accuracy as the flagship units and will satisfy the needs of most club and regional competitors.
However, as teams move toward national-level competition, temperature measurement becomes increasingly valuable. At that point, the Needle Probe or Dual Technology models begin to justify their higher cost through better setup information and improved race engineering capabilities.
The good news is that whichever HPM5 model you choose, you'll be using one of the most accurate and data-focused tyre pressure systems currently available for karting.
