Low thermal mass
With an anodised, machined aluminium body this probe is rugged and durable. Our probe length adjuster is made from a low thermal mass engineering material to avoid acting as a heat sink and affecting your readings.
 
Adjustable depth
There is a screw adjuster and locking nut so that the tyre can be probed at a consistent depth. It’s important for the depth to be consistent as tyre temperatures will vary considerably with depth.
A depth of between 3 and 5mm is recommended. The probe can be adjusted up to 15mm which will puncture most tyres. To avoid punctures the needle should obviously not be inserted too deep and the probe should be inserted into the tyre blocks only and not the grooves/voids or sides. Take care with very worn tyres.
 
Quick response
We’ve paid special attention to ensuring the thermocouple is as quick response as possible. We tested many probes from different brands and found a huge variation in response times (and accuracy).
 
After insertion it typically takes 2 seconds for the probe to reach 90% of the final temperature, 3 seconds for 95% and 4 seconds + for the temperature response to level out.
The gauge even shows Up or Down arrows if the temperature is changing. These will disappear when stable.
 
Comes with hard carry case
It’s important to insert the probe tip perpendicular to the tyre. If inserted at an angle this can cause damage or breakage to the probe tip. Accidental tip damage is not covered by the guarantee.
Avoid heat sources: Temperature accuracy will be affected if e.g. the gauge or probe are heated (or cooled). So, do not leave the gauge and probe near sources of heat or where large thermal gradients may be expected e.g. in direct sunlight, on top of engine, near heaters or fans etc.
Car setup, tyre pressures, track conditions and driving style will all affect the bulk tyre temperatures.

It does not make sense to compare readings from different car or tyre types or different probe depths.
