Fluke 771 Milliamp Process Clamp Meter

Are you spending time:

• Taking mA measurements by removing a wire and breaking the loop
• Calling the control room to isolate a loop
• Testing analog input/output on a console
• Troubleshooting devices with mA inputs and outputs
• Repairing intermittent or erratic 4-20 mA loops
• Going back to the shop to get extra tools

If you need more time in your busy day take a good look at the Fluke 771 mA Clamp Meters. It’s designed to save you time, and money, by eliminating time wasting activities. Now you can troubleshoot and repair 4-20 mA loops without breaking the loop or bringing down the system.

Here are some specific ways the Fluke 771 Clamp Meters will help you:
