Fluke 724 – Overview The Fluke 724 is a versatile temperature calibrator that can source and measure multiple thermocouple and RTD types, along with ohms and volts. It also has a loop-power feature to power transmitters while measuring mA. Its dual display shows source and measurement simultaneously, ramp/step functions streamline calibration work, and its rugged design with battery power makes it suitable for field use. Key Features Sources and measures 12 thermocouple types and 7 RTD types Measures volts, ohms, resistance-temperature detectors (RTDs) Supplies 24 V loop power with simultaneous mA measurement Dual-line display shows source output and measurement at same time Ramp, step (25% / 100%), and auto-step functions for fast calibration Memory store for saving frequently used setups Backlight for low-light conditions Runs on 4 AA batteries with easy-access battery door Rugged, field-friendly design; simple controls (few menus) Technical Specifications Model: Fluke 724 DC Voltage (measure/source): up to 30 V measure; up to 10 V source; accuracy ~0.02% + 2 counts Current DC (measure with loop power): up to 24.000 mA; accuracy ~0.02% + 2 counts Millivolt TC input: -10.00 mV … +75.00 mV; accuracy ~0.025% + 1 count Resistance ranges: 0 … 3,200 Ω; resolution down to 0.1 Ω; accuracy varies with wire-configuration and range Thermocouple accuracy (examples): • J, K, T, E: ~0.7-0.8 °C at higher ranges, ~1.0-1.2 °C at low ranges • R, S, B: higher error ~1.4-1.8 °C in upper ranges RTD accuracy (examples): Pt100 (385): ~0.33 °C; Pt200 (385): ~0.2 °C; Ni120: ~0.2 °C Loop Power: 24 V, short-circuit protected; maximum current ~22 mA Operating Temperature: -10 … +55 °C Storage Temperature: -20 … +71 °C Humidity: non-condensing; 90% at 10-30 °C; decreasing at higher temp ranges Safety / EMC Ratings: CSA, EN standards; Class B emissions, industrial immunity Size / Weight: ~96 × 200 × 47 mm; ~650 g Battery: 4 × AA alkaline; typical battery life ~25 hours Applications Calibrating temperature sensors/transmitters using TC or RTD types Having one tool for sourcing and measuring multiple types of temperature inputs Loop-powered transmitter testing in field without needing external power Performing ramp or step tests for linearity verification Why Choose Fluke 724 Multi-signal capability reduces the number of instruments needed Dual display enhances clarity and speeds up calibration work Loop power support simplifies dealing with transmitters without extra gear Rugged battery-powered design built for field reliability Order Now The Fluke 724 Temperature Calibrator is available for purchase.
