Fluke 726 Precision Multifunction Process Calibrator

The Fluke 726 is a high-accuracy, dual-channel process calibrator for the process industry, delivering 0.01% accuracy to measure, source, and simulate nearly all process signals—ideal for calibrating transmitters, sensors, valves, and instruments in the field.

Key Features

0.01% High Accuracy: Precision measurement and sourcing for critical process calibration.
Dual Independent Channels: Simultaneously measure, source, and monitor two process signals (e.g., mA + pressure).
Comprehensive Signal Coverage:
- Measure: Volts, mA, RTDs, thermocouples, frequency, resistance, pressure (with modules).
- Source/Simulate: Volts, mA, RTDs, thermocouples, frequency, pressure, pulse trains.
Integrated Pressure Switch Test: Capture set point, reset point, and deadband of pressure switches.
HART Mode: Inserts 250 Ω resistor for HART-compatible mA measurements/sourcing.
24 V Loop Power: Power transmitters while measuring their mA output.
Transmitter Error % Calculation: Directly read error percentage—no calculator needed.
Memory Storage: Save up to 8 calibration results for later analysis.
Frequency Totalizer & Pulse Train: Enhanced flowmeter testing.
Custom RTD Curves: Support calibrated RTD probes for precision temperature work.
