The Haffmans GCD Gauge Calibration Device is a dedicated precision instrument for calibrating pressure gauges and digital pressure sensors. Universally applicable, it can be used for all kinds of pressure calibrations and is compliant with international standards. By simply connecting a compressed gas supply to the inlet, attaching the pressure measurement device that needs to be checked to the outlet, and setting the desired pressure with the reducing valve, the pressure can be compared with the reading and calibrated.
