Fluke 772 Milliamp Process Clamp Meter

Overview

The Fluke 772 Milliamp Process Clamp Meter is designed to eliminate one of the most time-consuming tasks in process control: breaking the 4–20 mA loop. Built by Fluke, the 772 enables fast, non-contact measurement of milliamp signals while the system remains fully operational.

With the ability to measure, source, and simulate mA signals, the Fluke 772 is an essential tool for technicians working on PLCs, transmitters, valves, and control loops who need accurate diagnostics without interrupting production.

Why You Should Buy It

The Fluke 772 is ideal for instrumentation and control technicians who want to work faster and safer. By eliminating the need to disconnect wiring or shut down processes, it reduces troubleshooting time and prevents costly disruptions. Its ability to both measure and source mA signals makes it a versatile, all-in-one solution for maintaining and diagnosing 4–20 mA loops.

FAQ – Fluke 772

Can the Fluke 772 measure 4–20 mA without breaking the loop?
Yes. The clamp allows non-contact measurement of mA signals while the loop remains active.

Can it source or simulate mA signals?
Yes. It can source and simulate 0–24 mA for testing transmitters, valves, and control devices.

What is the maximum current it can measure?
Up to 99.9 mA DC using the clamp.

Is it suitable for PLC and control system I/O testing?
Yes. It is specifically designed for PLC analog input/output diagnostics.

Does it include data logging?
No. The Fluke 772 focuses on real-time measurement and calibration rather than logging.
