Crystal HPC50 Series Ex Pressure Calibrator

IECEX Ex ia IIC T4/T3 Ga

The intrinsically safe Crystal HPC50 delivers laboratory-grade accuracy in a truly versatile, hand-held, hazardous area certified field instrument.

The HPC50 will calibrate pressures from vacuum to 10000 psi / 700 bar with accuracy up to 0.035% of reading. It is ideal for process control applications such as verification or calibration of pressure gauges, transducers, transmitters, switches or safety valves.

Configurable with single or dual-range internal pressure sensors, the HPC50 will also accept external APMi modules to read from up to 4 individual or 2 differential pressures. An optional barometric module provides the choice of absolute pressure measurements. In addition, ambient and process temperatures can be read separately or simultaneously using optional ATMi modules.

Every HPC50 comes with an ISO/IEC 17025 accredited calibration report, showing data over the full temperature compensated range.
