Voltage Electronic Racing Gauge

PRO3 Voltage Electronic Racing Gauge

Voltage Electronic Racing Gauge Measurement Range is 8V ~ 18V.
Voltage Electronic Racing Gauge Measurement Range is 8V ~ 18V.

Voltage electronic racing gauge using micro-control technology to resolve the pointer movement angle of 270 degrees into 4088 micro steps. It can detect subtle voltage changes. The vehicle power system is connected in series to monitor the battery voltage. Voltage electronic racing gauge measurement range is 8V ~ 18V. The battery voltage must be maintained at 13V before start up the vehicle. If the voltage is too low, then it will need to check about the battery life.


  • A brushless motor is use to subtract frictional resistance.
  • Use micro-control technology to resolve the pointer movement angle of 270 degrees into 1088 micro steps.
  • Balanced pointers are used to eliminate pointer inertia during rotation.
  • Special orange aluminum ring can fit in any driving space.
  • Built-in 6-segment dimming of LED backlight.
  • 12V vehicle voltage. Safety design to protect overvoltage (18V) blocking and reverse current.
  • Small button design to expand user interface also can transfer as an auto shift light. It will light up at the same time when detect to warning value.
  • Peak Record: Record the current highest value for users to know the maximum value of data.
  • LED Backlight Memory: Available setting the backlight color while the headlight is open or off. It will show the setting backlight in next time switch.


Connect to the vehicle battery and measure the voltage value is maintained above 12V. Before starting the vehicle, it must be maintained above 13V. For those vehicles with high power consumption components or batteries that have been used for a period, enough voltage can be ensured to start.
