Fluke 725

Fluke 725 – Multifunction Process Calibrator

Overview

The Fluke 725 is a versatile field calibrator designed to source, measure and simulate key process signals for maintenance, testing and calibration. It handles current, voltage, temperature sensors, resistance, frequency and pressure (with optional modules). It includes built-in 24 V loop power so you can power transmitters while measuring output. The device is rugged, compact, has simple controls and a backlit display for ease of use in tough environments.

Key Features

• Source and measure DC current (mA), DC voltage, resistance, frequency, temperature, pressure modules

• Built-in 24 V loop power supply for powering transmitters during tests

• Simultaneous measure and source capability so input and output can be seen at same time

• Support for thermocouples and RTDs for both measure and source functions

• Source/simulate pressure via compatible pressure modules for valve or I/P tests

• Auto-step and auto-ramp functions for fast linearity or span tests

• Store and recall frequently used calibration setup configurations

• Backlit display for visibility in low-light field conditions

• Rugged, easy-to-carry design with simple user interface

Technical Specifications

• Model: 725

• DC Current (source / measure): up to 24.000 mA, accuracy ~0.02 % + 2 counts

• DC Voltage (measure / source): ranges include 100.00 mV, up to ~30.000 V; accuracy ~0.02 % + 2 counts

• Resistance ranges: from low ohm (~0 Ω) up to ~3200 Ω; accuracy varies with range (~0.1 to 1.0 Ω depending on wiring method)

• Frequency range: up to ~10.00 kHz (or higher in some modes like CPM), resolution ~0.1 unit; accuracy ~0.05 % + 1 count

• Thermocouple support: many types (J, K, T, E, etc.), with resolution 0.1 °C or better; accuracy depends on type and range

• RTD support: standard types (Pt100, Ni120, etc.), measure and source; accuracy typically ~0.2-0.5 °C depending on type and range

• Pressure support: via optional modules; accuracy per module (e.g. ~0.025 % of range for some modules)

• Loop power output: 24 V, capable of powering transmitters while measuring current

• Excitation current for resistance/RTD sources: varies with range; low ranges may allow few mA, higher ranges less

• Operating temperature: -10 °C to +55 °C

• Storage temperature: approximately -20 °C to +71 °C

• Power supply: four AA batteries; typical battery life depends on usage but field-rated for many hours

• Size (H × W × D): ~130 × 236 × 61 mm

• Weight: ~0.65 kg

Applications

• Calibrating temperature and pressure transmitters

• Verifying process signal outputs in mA, volts or frequency in control systems

• Flow meter and I/P valve testing with pressure modules

• Field maintenance and troubleshooting where test source and measure are needed simultaneously

• Performing linearity and span checks with auto-step or auto-ramp features

Why Choose the Fluke 725

• Combines many calibration functions into one unit to reduce tool load

• Simultaneous source/measure and loop power save time and simplify field calibration

• Rugged build and intuitive interface make it ideal for harsh environments

• Optional pressure module support expands functionality for process instrumentation
