Fluke 773 Milliamp Process Clamp Meter Industrial 4–20 mA Loop Clamp Meter with Source, Simulate and Loop Power for PLC and Process Control Systems

Product Description
The Fluke 773 Milliamp Process Clamp Meter is a professional industrial diagnostic tool designed for fast and accurate measurement of 4–20 mA process signals without breaking the loop. This advanced process clamp meter allows technicians to troubleshoot transmitters, valves, and PLC control systems while the process remains live, significantly reducing downtime and maintenance costs. With best-in-class accuracy of 0.2% and 0.01 mA resolution, the Fluke 773 delivers highly precise measurements for industrial automation and instrumentation environments.

Unlike traditional multimeters that require opening the loop, the Fluke 773 can measure up to 99 mA using its clamp jaw, making it ideal for process engineers and instrumentation technicians. It also supports sourcing and simulating 4–20 mA signals, provides 24 V loop power, and measures DC voltage for testing sensors and control devices. For engineers, maintenance teams, and industrial plants in Bangladesh, the Fluke 773 is a reliable solution for process control diagnostics.
