Fluke FLUKE-724 Temperature Calibrator

This handheld temperature calibrator provides temperature sourcing and measurement for sensors and transmitters in industrial environments. It supports both thermocouples and RTDs, Plus voltage and resistance checks, enabling single-instrument field verification and transmitter calibration with a clear dual display and straightforward button controls.

• 0.02% accuracy improves measurement confidence in diagnostics
• 0.1°C resolution for precise temperature simulation and readback
• Sources 12 thermocouple and seven RTD types to cover sensor ranges
• Loop power supply with mA measurement to power and verify transmitters
• Ramp and step functions for automated linearity and response testing
• Four AA cells deliver around 25 h battery life for extended field use

• Suitable for commissioning and maintenance of temperature transmitters
• Ideal for on-site RTD sensor verification in process plants
• Used with thermocouple probes for sensor simulation during calibration
• Can be used for functional checks of 4–20 mA temperature loops
• Used for Rapid linearity testing of transmitter outputs

It supports a wide range of thermocouples (including J, K, T, E, R, S, B, L, U, N) and multiple RTD types such as Pt100 (385 and 392 JIS), Pt200, Pt500, Pt1000 and Ni120.

The instrument can source temperature-equivalent signals, provide loop power up to 24V and measure loop current simultaneously on the dual display for end-to-end transmitter checks.

It operates between −10°C and 55°C and is specified for humidity ranges from 90% at 10–30°C down to 35% at 50–55°C without condensation.

Resistance coverage extends to 3200 Ω with specified accuracy bands and selectable 0.1 Ω resolution for low-Ω ranges to support conversion to temperature values.
