AMETEK Test & Calibration Instruments has introduced two intrinsically safe pressure calibrators for use in hazardous oil, gas, petrochemical, and many other applications.

The dual-sensor JOFRA HPC552 Ex handles two pressure ranges in a single unit to reduce cost and simplify use. Both the dual-sensor and the single-sensor Model HPC550 Ex include LCD backlighting for enhanced visibility in difficult operating conditions.

Suited to a broad range of applications from simple tool type jobs to complex calibration applications in custody transfer systems, features include user configurable information display, 15 different pressure units, mA input and percentage error calculation. Both models have ATEX / IECEx certification for use in potentially explosive situations. They also have a temperature reference probe input that turns the pressure calibrator into an ATEX certified reference indicator that can be ordered with a selection of reference probes.
