The intrinsically safe Crystal HPC51 pressure calibrator delivers laboratory-grade accuracy in a versatile, hand-held, zone 0 hazardous area certified field instrument.

The HPC51 will calibrate pressures from vacuum to 10,000psi / 700 bar with accuracy up to 0.035% of reading. Ideal for process control applications such as verification or calibration of pressure gauges, transducers, transmitters, switches or safety valves.

Crystal HPC51 calibrators are compatible with Crystal APMi intrinsically safe external pressure modules to read up to 4 individual or 2 differential pressures.

An optional barometric module provides the choice of absolute pressure measurements. Ambient and process temperatures can also be read separately or simultaneously using the Crystal ATMi intrinsically safe Pt100 RTD module.

Every HPC51 comes with an ISO17025 accredited (NATA equivalent) calibration report, showing data at 5 points over the temperature compensated range of -20 to +50°C.
