Description

The Fluke 725Ex is an intrinsically safe, multifunction process calibrator designed for use in hazardous areas where explosive gases may be present. It’s a versatile tool that can measure and source various electrical signals, as well as measure pressure with optional pressure modules.

Key Features:

Intrinsic Safety:
- Primary Key Feature: Meets stringent safety standards (Class I, Division 1, Groups B, C, and D) to prevent ignition in explosive atmospheres.
Multifunctionality:
- Measures and sources a broad range of electrical signals: DC voltage, DC current, resistance, frequency, and temperature (RTDs and thermocouples).
- Expands capabilities with optional pressure modules for comprehensive pressure measurements.
Two-Channel Operation:
- Enables simultaneous source and measure functions, streamlining transmitter calibration.
Rugged Construction:
- Built to withstand harsh field conditions with a durable design and protective rubber boot.
User-Friendly Interface:
- Intuitive controls and a clear display simplify operation, even in challenging environments.
Pressure Measurement:
- Compatible with a range of Fluke-700PEx pressure modules for accurate pressure measurements up to 3,000 psi/200 bar.
Loop Power:
- Provides 24V loop power for powering transmitters during calibration.
Communication:
- Optional HART communication capabilities for interacting with HART-enabled devices.

Applications:

Oil and Gas: Calibrating instruments in refineries, offshore platforms, and other hazardous locations in the oil and gas industry.
Chemical Processing: Calibrating process instruments in chemical plants and other hazardous industrial environments.
Pharmaceutical Manufacturing: Calibrating equipment in pharmaceutical production facilities.
Other Hazardous Industries: Used in any industry where there is a risk of explosive atmospheres, such as mining, petrochemical, and food processing.

By combining safety, versatility, and accuracy, the Fluke 725Ex is a valuable tool for technicians and engineers working in hazardous environments.
