  Comparison Test Pump
Comparison Test Pumps are used For Calibrating pressure gauges against master pressure gauge. The master gauge to be periodically checked on dead weight pressure gauge tester. Two gauge connectors are provided for connecting master gauge and gauge to be tested to the same hydraulic pressure. Screw Pump, Oil operated, will generate pressure in the circuit. Permits easy and accurate setting of pressure.
