The Fluke Calibration 7526A Precision Process Calibrator is a benchtop calibration instrument designed for temperature and pressure process instrumentation. The datasheet positions the 7526A as a single-box tool that sources and measures DC voltage, current, and resistance, simulates and measures RTDs and thermocouples, and accepts external pressure modules for precision pressure measurement. It is offered as a balance of economy and accuracy for process calibration work.
Per the datasheet, the 7526A is used to calibrate RTD and thermocouple readouts, pressure gauges, temperature transmitters, digital process simulators, data loggers, and multimeters. The instrument simulates and measures nine RTD types and thirteen thermocouple types, sources DC voltage from 0 to 100 V, sources DC current from 0 to 100 mA, and measures 4-20 mA loop current using the included 24 V DC transmitter loop power supply. With Fluke 525A-P Series Pressure Modules, the 7526A also performs pressure measurement to within 0.008 % of reading as stated by the datasheet.
ValueTronics International has supplied new and used test and measurement instrumentation since 1992 from our 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Every {{CONDITION}} 7526A that passes through our facility is inspected, performance-verified, and graded by our in-house technical team before it ships, with calibration options available to match your quality system requirements.
Fluke Calibration is the calibration-instrument division of Fluke Corporation, which itself sits within the broader Fortive group following the 2016 spin-off from Danaher. The Fluke Calibration product line traces back through several decades of precision metrology development and includes process, electrical, RF, temperature, pressure, and flow calibration instruments under a single brand.
