Fluke 726 Precision Multifunction Calibrators

The Fluke 726 Precision Multifunction Calibrator simultaneously measures, sources, and displays process signals across two independent channels. Built for field technicians and calibration engineers, this instrument delivers 0.01% general accuracy while supporting voltage, current, resistance, frequency, temperature, and pressure measurements and sourcing. Dual-channel operation enables concurrent sensor and transmitter testing without reconfiguration.
