4Inch 100MM Explosion-proof Digital Pressure Gauge

• Product Description

Digital pressure gauges include precision digital pressure gauges, handheld precision digital pressure gauges, diaphragm digital pressure gauges, benchtop precision digital pressure gauges, and failure-proof digital pressure gauges.

Precision digital pressure gauges not only solve the problem of standard pressure calibration but also better meet the comprehensive testing needs in the field. They can be used as high-accuracy calibration standards (gauges) for the calibration and verification of pressure transmitters. These portable instruments can operate on both AC and DC power, measuring current simultaneously with pressure and displaying the results on an LCD screen, and also have a 24VDC output. A microprocessor automatically compensates for zero-point drift, temperature drift, and nonlinearity, ensuring high accuracy within the instrument's operating conditions. Single-range, single-function precision digital pressure gauges can replace traditional precision pointer pressure gauges.
