Product Introduction
HQ711 applies a new generation of dynamic ratio measurement circuit with the selected imported sensor. The accurate temperature compensation, greatly improves the accuracy and long-term stability of pressure measurement. Because of the Micro power consumption design, it decreases the changing frequency of battery on a large scale. It is very suitable for field pressure measurement, laboratory use, general pressure gauge and precision pressure gauge measurement. It can completely replace the pointer precision pressure gauge.


Application description

1. Adjusting common pressure gauge             
2. Adjusting precision pressure gauge
3. Adjusting sphygmomanometer
4. Adjusting other pressure instruments
5. High precision pressure measurement

Using environment
