Ametek's dual-sensor JOFRA HPC552 Ex pressure calibrator handles two pressure ranges in a single unit. Both the dual-sensor and the single-sensor Model HPC550 Ex include LCD backlighting for enhanced visibility in difficult operating conditions.
The HPC550 and HPC552Ex bring laboratory accuracy to an on-site, field-usable instrument with intelligent features such as a 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 feature a temperature reference probe input that turns the pressure calibrator into an ATEX certified reference indicator, which can be ordered with a selection of reference probes.
