LED option: Red

Compared to 1/32 DIN sized gauges, this new gauge with round appearance matches with other round gauges on the instrument panel/dashboard. It is also easier to be mounted to an A-pillar pod.

This digital automobile gauge can be used to measure temperature, pressure and other important parameters, such as battery voltage and air/fuel ratio. Its bright LED display is easy to read from a distance compared to many dim LCD type digital gauges. The programmable alarm will turn on a blue LED in the front panel to get the driver's attention if the temperature/pressure is above the setting point. It will also close a relay output port that can be used to turn on a buzzer, shut off the fuel, or turn on a cooling fan. The meter stores the peak temperature/pressure with time stamps that can be checked later. It can also operate in the peak holding mode so that only the maximum value is displayed. The brightness of the LED display can be synchronized with headlights. When the headlight is turned on at night, the display will be dimmed by the illumination signal. It can also be dimmed directly on the key pad. Developed based on industrial grade instruments, this four digits gauge offers up to 10 times the resolution and accuracy of most 3 digits gauges on the market. The gauge also includes cold junction compensation circuit to further reduce the temperature drift when a thermocouple sensor is used.

Please note, this gauge can only be set to measure one type of sensor at a time. It can't measure multiple sensors simultaneously.
