The MGC series is using quality mechanical gauges as pressure reference. Connect the reference gauge and the unit-under-test to the hydraulic pump and calibrate. The MGC-LOW consists of 2 or 3 dual-scaled precision pressure gauges with ±1% F.S. accuracy and a hydraulic handpump fitted with hose, valve, and couplings. The MGC-HIGH consists of 3 or 4 dual-scaled precision pressure gauges with ±0.6% F.S. accuracy and a hydraulic jack pump fitted with hose, valve and couplings. The gauges provide a clear indication of pressure for comparison to the unit-under-test. The operator can then identify the extent of any error and adjust or replace faulty pressure indicators. Major Feature: Accuracy to ±0.6% F.S. of connected gauge, Pressure range 0 to 300 bar, 2 different models, Pressure units bar and kg/cm2, dual scale, Dual scale and easy-to-read gauges, Hydraulic pumps
