Description
The FLIR CM57-2 Flexible Clamp Meter measures AC current up to 3000 A with an 18-inch flexible coil that wraps around conductors a rigid jaw could never reach — bundled cables, tight switchgear, and large bus bars. Choose the standard or kit configuration where offered.
The CM57-2's flexible probe snakes into crowded cabinets while the meter body and backlit display stay in your hand, with true-RMS accuracy, inrush measurement, and a worklight for dark enclosures. Bluetooth METERLiNK® connectivity logs and shares readings through the FLIR app.
- Flexible clamp meter designed for difficult current measurements in tight spots
- 18-inch (45 cm) flexible coil clamp wraps around multiple conductors or large cables — ideal for multiple-conductor measurements and double-wrap requirements
- True RMS AC current ranges from 30.00 A to 3000 A
- Dual LED worklights provide better visibility in dark or poorly lit areas
- Stream live data in real time over Bluetooth to the METERLiNK app: visually compare log files, customize alarm thresholds, create reports, and share readings instantly
- Data record mode stores 20,000 points at a 1-minute sample rate
- IP54 rated and 3 m drop tested
Typical Applications
- Switchgear and panel work
