AR168 Digital Pressure Gauge

The AR168 Digital Pressure Gauge is a professional high precision, high range, high resolution digital pressure gauge for indoor temperature measurement with a large screen display. It can quickly measure the pre-blue detection pressure value and has a dual channel that can simultaneously detect the pressure difference between two detection ports. 

It is most commonly used in natural gas pipelines, air-conditioning refrigeration and ventilation systems , mechanical hydraulics, plastic molding, ceramic products and production industrial equipment pressure detection.
