Crystal HPC41 Pressure / mA Calibrator

The Ametek Crystal HPC41 is the world's first combined pressure and mA loop calibrator to be fully temperature compensated from -20 to +50°C. With a built-in RTD thermometer, you can count on a high level of accuracy whether you're measuring pressure, current, voltage or temperature.

The HPC41 is compatible with Crystal's APM CPF series of external pressure modules and an optional barometric module provides the choice of absolute pressure measurements.

Every HPC41 comes with an ISO / IEC 17025 (NATA equivalent, A2LA accredited, ILAC recognised) calibration report, showing data over the full temperature compensated range.
