Large Flex Clamp Meter with Bluetooth
Description
18″(45cm) 3000 A true RMS AC flexible current clamp meter with Bluetooth
The FLIR Flex Clamp Meters with Bluetooth are ergonomic tools designed to simplify difficult current measurements. Made with a narrow flexible coil clamp, the FLIR CM55 and CM57 let you easily take measurements in tight or awkward spots—a difficult task with a traditional hard jaw clamp meter. With Bluetooth communication for remote viewing and data transfer to iOS and Android devices via the FLIR Tools Mobile app, you can analyze and share data fast right from the job site.
Take accurate measurements in tight or awkward spots—tricky conductors conquered:
  • Snake the coil around obstacles with ease, even in deep, crowded cabinets.
  • True RMS AC up to 3000 A for multiple conductor measurements.
  • Inrush current function for equipment start-up spikes.
Easy inspection and navigation—designed with your convenience in mind:
  • Standalone flexible clamp meter displays the readings you need.
  • Bright, dual-LED worklights provide built-in illumination for dark cabinets.
  • Drop tested to 3 m, portable, lightweight, and tangle free without compromising measurement range.
Remote viewing from a safe distance—transfer and view data on mobile devices with the FLIR Tools Mobile app:
  • Connect to iOS and Android smartphones or tablets.
  • Multiple units wirelessly connect for remote viewing of multiphase systems.
  • Data recording for trend analysis transferable via Bluetooth.
