FLIR Flexible Clampmeters CM55 & CM57

Ergonomically designed the FLIR CM55 and CM57 clamp meters are specifically designed to access difficult or awkward spaces. The unique design enables measurements to be taken where traditional hard jaw clamp meters would find it impossible to access. Featuring Bluetooth communication technology, the FLIR CM55, and CM57 flexible clamp meters enable remote viewing and data transfer to iOS® and Android™ via the FLIR Tools Mobile App.

Using the FLIR flexible clamp meters couldn’t be easier, simply turn the clamp lock counter-clockwise to release the flexible jaw clamp. The narrow coil can then be snaked around obstacles with ease even in deep, dark or cramped cabinets. Bright, dual-LED work lights provide built-in illumination to help you see in dark spaces and overcome shadowing.

Packed with a range of smart, easy to use functions the True RMS CM55 and CM57 clamp meters really are THE essential test instrument for any electrical engineer’s toolbox.

Flexible clamp meters are test tools widely used by electricians and technicians to measure the current flowing through conductors. The instruments enable engineers to safely conduct tests and gather information. They help determine why a system or piece of electrical equipment is not operating correctly. Some of the most common applications are

  • Power and utility installation, maintenance and diagnostics

  • Electrical contractors and engineers

  • Building, facility plant, and maintenance personnel


Q: What is the difference between the FLIR CM55 and the FLIR CM57 clamp meters? A: Both meters provide readings with a high level of accuracy and are functionally the same. The only major difference is the size of the coil. The CM55 has a 10" flexible clamp and the CM57 has an 18" flexible clamp.
Q: How are the flexible clamp meters powered?
A: Both models are powered by two (2) 1.5V AAA batteries.
Q: Where can I access the FLIR Tools ® App?
A: The free Wi-Fi app available to download for both Android or iOS devices (iPad or iPhone) from the FLIR website.
Q: Is there a maximum distance that can be achieved via Bluetooth?
A: A maximum range of up to 10m or 32ft
