Calibration Software

A “best fit” for your process calibration
requirements

In today’s competitive global markets with the need to
continuously cut manufacturing costs, precise temperature
and pressure process control is required to maintain product
quality, reduce waste and ensure compliance to regulatory
standards. Regular calibration of a wide variety of process
measurement instrumentation is required to meet these

standards. The 7526A Precision Process Calibrator puts all the
necessary tools for process instrumentation calibration into
one box. The 7526A simulates and measures nine RTD and
thirteen thermocouple types, accurately measures pressure
to within 0.008 % of reading when combined with Fluke
525A-P Series Pressure Modules, sources and measures dc
voltage from 0 to 100 V to within 0.004 % of reading, sources
dc current from 0 mA to 100 mA, accurately measures dc
current to within 0.01 % from 0 mA to 50 mA and supplies
24 V dc loop power. Combined with MET/CAL
