Fluke 771 Milliamp Process Clamp Meter

The Fluke 771 Milliamp Process Clamp Meter is a high-precision, non-intrusive tool designed for measuring 4-20 mA signals in process control and automation systems without breaking the loop. With best-in-class 0.2% accuracy, 0.01 mA resolution, and a detachable clamp for tight spaces, it simplifies troubleshooting and minimizes downtime. Ideal for measuring mA signals in PLCs, control system analog I/O, and transmitters, the Fluke 771 allows technicians to quickly diagnose issues without interrupting critical operations.

Equipped with a dual backlit display that shows both mA measurements and the percent of a 4-20 mA span, this meter provides clear insights into system performance. Its built-in LED spotlight makes working in dark enclosures easier, while the Hold function lets you capture fluctuating readings for later review. Capable of also measuring 10-50 mA signals in older systems, the Fluke 771 is a versatile and efficient solution for process troubleshooting.
