The FLIR CM57-2 is a versatile clamp meter intended for demanding current measurements. The CM57-2's 18-inch (45.72 cm) flexible coil clamp enables you to take measurements in small spaces, making it suitable for multiple-conductor measurements and double-wrap requirements. The meter also has twin LED work lights for improved visibility, and the AC current ranges from 30.00 A to 3000 A. Using the METERLiNK® software, you can stream live data from the CM57-2 to your mobile device over Bluetooth, graphically compare log files, modify alert thresholds, produce reports, and instantaneously share readings with team members.
