HPC40 Series Pressure Calibrator

Brand: Crystal Engineering by Ametek

The HPC40 Series handheld pressure calibrator is the world's first combined pressure and mA loop calibrator to be fully temperature compensated from -20 to 50°C.

You can count on the same accuracy whether measuring pressure, current, voltage, or temperature.
