High Accuracy Pressure Calibrators with Intrinsically Safe Rating and LCD Backlighting

Press release date: Oct 19, 2011

New AMETEK/JOFRA® instruments include dual-sensor and single-sensor models

Two intrinsically safe pressure calibrators for use in hazardous oil, gas, petrochemical and many other applications have been introduced by AMETEK Test & Calibration Instruments. 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.

Applications include:
  • Oil & Gas production & distribution
  • Chemical Processing
  • Aircraft/automotive refueling
  • Printing/coating
  • Hospitals
  • Pharmaceuticals
  • Sewerage treatment
  • Coal mining
  • Grain handling
  • Metalworking
  • Woodworking
  • Sugar refining

    The HPC550 and HPC552Ex bring laboratory accuracy to an on-site, field-usable instrument. They are well suited for a broad range of applications from simple tool type jobs to complex calibration applications in custody transfer systems. Intelligent features include user configurable information display, 15 different pressure units, mA input and % 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.

    The JOFRA HPC550/HPC552Ex family of handheld pressure calibrators is part of a comprehensive line of pressure, temperature, and signal calibration products marketed by AMETEK under the JOFRA® ( and MANSFIELD & GREEN® brand names.
