Pressure Gauge Testers

This tester is the combination of a mercury-column scale and a pump unit that examines a pressure gauge being tested by comparing it with the mercury-column scale.
The tester is compatible with either pressure tests or vacuum tests by valve switching.
Factory-adjusted for an ambient temperature of 20 oC, the tester needs adjustments when used at a different ambient temperature.
