[ Function ] --- Turbo boost pointer meter, used to monitor boost pressure & vacuum compression levels of car's turbo & supercharged engine. Avoiding turbo over boost causing other possible engine issues.

[ Clear Display ] --- White dial with blue LED light, clear red pointer+accurate scale and numbers, can clearly show the press / vac. Easy to read, the LED light allows views very well even in the darkness, convenient to use.

[ Measurement Range ] --- The turbo boost gauge reads vehicle's boost levels from 0 to 30 psi & vacuum compression levels from -30 to 0 inhg. High level of accuracy and sensitivity, easy to operate.

[Key Features] The transmitter features high sensitivity, high accuracy, strong overload resistance and anti-interference ability, long-term stability and reliability.

[4~20mA Output Signal] By using unique stress isolation technology, precise temperature compensation and high stability amplification processing, the signal of the measured medium will be converted into 4~20mA output signal.

[No Need to Adjust Accuracy] Highly integrated sensor and amplifier circuits; Die-cast aluminum alloy is adopted, zero point and accuracy of circuit board need not be adjusted
