JOFRA HPC550/552Ex calibrators feature deadweight tester accuracy in a modern digital package. The HPC550/552Ex can be used in a very broad range of applications from simple tool type jobs to complex calibration jobs in custody transfer systems. Including potential hazardous areas in Oil, Gas and Chemical industries.
The HPC550/552Ex series has been designed to meet high accuracy pressure calibration applications and faciliate your tasks. HPC550/552Ex offers features such as user configurable information display, 15 different pressure units, transmitter supply, mA input, % error calculation, voltage measurement, serial communication, and external pressure module capability. The accuracy of the HPC550/552Ex calibrators is specified in % of reading to ensure an even better accuracy and wider applicable pressure range. The HPC is temperature compensated from 0 to 45ºC/32 to 113ºF for on-site operation. It is a truly superior pressure calibrator for laboratory and field use, bringing laboratory accuracy into the field.
