Fluke 712B

RTD Temperature Calibrator

The Fluke 712B Temperature Calibrator is a handheld instrument used to measure and simulate resistance temperature detectors. It supports measurement and source functions for multiple RTD types with resistance ranges from 1 Ω to 4000 Ω. The unit also measures 4 to 20 mA signals while sourcing an RTD output for loop calibration tasks.
