peak hold Digital Air Pressure Gauge ,explosion-proof LCD gauge,4 digit battery supply digital oil gauge

QYB109 Intelligent pressure gauge is made with entire electronic structure, and uses battery as power supply.

It is easy for field installation. QYB109 intelligent pressure gauges are using high accuracy piezoresistive pressure sensors, which is located in the front end of QYB109. The output signal of the pressure sensor is processed and amplified by high accuracy and low temperature coefficient amplifier, and then transferred to A/D switch to transform digital signal which can be processed by microprocessor.
