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 a cold junction compensation circuit to further reduce the temperature drift when a thermocouple sensor is used. Its compact size (24 x 48 mm or 1 x 2") takes less space than a 52 mm round gauge. (Please note, each gauge can only be set to measure one type of parameter at a time. It can't measure multiple parameters simultaneously).

For EGT measurement, the meter will work with all EGT sensors on the market, grounded or ungrounded. There is no input impendence matching requirement. It can display the temperature in either Celsius or Fahrenheit. The temperature measurement is cold junction compensated for high accuracy. Very few EGT gauges on the market have the cold junction compensation circuit. Most of them cost several times more than this gauge.

For boost pressure measurement, the meter will work with all MAP sensors as long as its pressure/output voltage relationship is known. It can display the pressure in either Bar, PSI, or user defined units with high resolution. However, it will not display the pressure with two different types of units on one scale, such as PSI for pressure range but inHg for vacuum range.

For water/oil temperature measurements, the meter can display from -199 °C to 250 °C (or -199 °F to 500 °F) with 1 degree accuracy when used with our RTD sensors. It will also work with our liquid tight thermocouple based sensors. In addition, it can work with a VDO 150 °C (300 °F) sensor with a limited display range (50-150°C, VDO sensor can only be displayed in Celsius with this gauge). The meter can work with either old style resistive pressure sensors or the modern style pressure transducers with linear voltage output. The meter offers a regulated 5V DC output for the power supply of the pressure transducer.

For air/fuel ratio measurements, it can be used to display either air/fuel ratio or lambda when interfaced with an Innovate Motorsports' LC-1/LC-2 wideband oxygen sensor controller. Please note, the meter cannot work as a standalone AFR with the oxygen sensor unless you are using a controller.
