High Precision Tire Pressure Gauge with Infrared sensor for tire temperatures and built in a Lap Timer

We have combined in one instrument

  • Digital Tire Pressure Gauge HPM4
  • Infrared Sensor for tire Temperature measurement
  • Lap timer

A new idea for a Tire Gauge !! 

Combining a highly accurate tire pressure gauge, Infrared pyrometer and a multi-driver Lap timer, this all in one unit can help to provide all of your tire data in once place and, thanks to its onboard memory, can store this data for multiple sessions. This means that you can review your data from previous sessions and compare how it has affected lap time.

Tire pressures showed on the display

Measure and save COLD and HOT tire pressures in the PRESSURE mode

Tire temperatures showed on the display

Measure and save AIR and TRACK temperatures and 12 points of tire temperature ( ex. EXTERNAL - INTERMEDIATE - INTERNAL ) for each sets


After taking Tire pressures and Temperatures, you can see the values that were recorded.

Tire pressures recorded on the display for each session

Tire Temperatures resumed on the display for each session


After measuring and saving Tire pressures and temperatures, Do you need a Stopwatch ?
Press and hold MODE button for 2 seconds and your instrument is a Stopwatch !

Press and hold MODE button to switch the instrument in the Stopwatch mode


Lap timer MODE

Now you can timing simultaneosly 4 drivers with 9 Split times for each drivers and Lap statistics

Timings 4 drivers simultaneosly


All your data in one instrument.

Tire pressure gauge with Infrared pyrometer and Lap Timer
  • DATE and TIME
  • AIR temperature - °C or °F
  • Languages Menu ITA - ENG - FRA
  • Backlit display with ambient light sensor intensity
  • Removable belt clip
  • IP55
  • MODE A - Absolute Split times mode
  • MODE I - Incremental Split Times mode

For each session you can recall :

  • DATE and TIME
  • AIR temperature
  • The 3 best LAPS for each driver
  • The Split Times for each LAP


By activating this function the pressure gauge HIPREMA 4 save automatically the HOT tire pressures without pressing any buttons.

PRESSURE gauge accuracy : 0.1%
  • Maximum error at 5 BAR : +/- 0,005 BAR -- ( 0.072 PSI )
  • Maximum error at 1 BAR : +/- 0,001 BAR -- ( 0.014 PSI )

  • Tire pressure sensor does not require calibration. The internal microprocessor automatically performs the procedure in order to reach a reliable measure at 100%.

  • BAR and PSI for tire pressure gauge
  • CELSIUS and FAHRENHEIT for temperature measurement

High ACCURACY infrared sensor
  • 1°C temperature Accuracy
  • 380°C Object Temperature
  • 35°FOV - Field of view

  • 25 Stopwatch sets of data
  • 25 Tire pressures and Temperatures sets of data

  • Italian
  • English
  • Français

Setup of the favourite rotation for saving pressures
  • Clockwise
  • Counterclockwise
  • Start from FRONT wheels or REAR wheels
Counterclockwise pressures rotation
Counterclockwise sense for saving tire pressures setup

NEW FEATURES with Firmware version 4.0.0

By the Firmware 4.0.0. it is possible to set the saving sequence of tire pressures ; it is possible to set the sense of the rotation, Clockwise or AntiClockwise and also the tire from where to start the saving pressures sequence. Rear Right or Left tire - Front Right or Left tire.
