  • Primary pressure standard accurate to ±0.1% of reading

These self-contained tester kits have everything you need for testing, setting, calibrating, and repairing your high-accuracy pressure instruments—except operating fluid. Testers come with a certificate verifying traceability to NIST-traceable standards.
Each kit consists of a two-stage hydraulic pump, two interchangeable piston assemblies (high- and low-pressure), a manifold with connectors, and an assortment of nonmagnetic, die cast zinc alloy weights. Precision-tooled weights are premeasured, marked with pressure values for each piston and come with a separate case.
Use the high-pressure piston for calibration pressures at maximum psi with a 75 psi resolution (see table at below); use the low-pressure piston to achieve 1/5 of the maximum pressure with a 15 psi resolution.
During operation, the manifold is pressurized until the weight assembly reaches a designated mark. A displacement valve lets you vary the pressure without using the pump handle or release valve. Once the correct pressure is achieved, simply reposition the needle on your gauge to the corresponding value.
Max psi in the table is with a 75 psi resolution using the high-pressure piston.
