The FLIR CM57-2 is a flexible clamp meter designed for difficult current measurements. With its 18-inch (45.72 cm) flexible coil clamp, the CM57-2 allows you to take measurements in tight spots, making it ideal for multiple-conductor measurements and double-wrap requirements. The meter also features dual LED work lights for better visibility, and AC current ranges from 30.00 A to 3000 A. Stream live data in real time from the CM57-2 to your mobile device over Bluetooth using the METERLiNK® app to visually compare log files, customize alarm thresholds, create reports, and share readings instantly with team members.
Get the accuracy you need in any space
Wrap the 18-inch flexible coil clamp around multiple conductors or large cables.
Dual LED worklights provide better visibility in dark or poorly lit areas so you can work more efficiently and safely.
