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.
