Industrial Thermal Imaging Clamp Meter with Datalogging, Wireless Connectivity, and IGM
The FLIR CM275 clamp meter combines thermal imaging with electrical measurement in a powerful inspection, troubleshooting, and diagnostic tool. Through Infrared Guided Measurement (IGM), it provides a fast, reliable way to identify hot spots and overloaded circuits from a safe distance. Confirm your findings with the clamp meter’s wide range of functions plus temperature readings. The FLIR CM275 provides wireless connectivity for direct connection to the FLIR Tools app and the FLIR InSite professional workflow management solution. When you choose the FLIR CM275 clamp meter, inspecting and servicing plant equipment and facilities becomes safer and more efficient.
Troubleshoot faster and more safely:
  • Identify electrical issues quickly with the power of IGM.
  • Scan entire targets for electrical issues with 160 × 120 thermal resolution.
  • Safely check for live connections using non–contact temperature measurement.
  • Pinpoint exact hot spot locations using laser and cross–hairs.
  • Easily reach awkward, dark locations using the narrow jaws and built-in worklights.
Diagnose efficiently:
  • Quickly verify problems, check loads, and validate hot spots.
  • Diagnose complex systems with high– and low-voltage measurement capabilities.
  • Use advanced electrical features including VFD mode, true RMS, and LoZ.
  • Expand measurement capabilities to 3000 A AC with FLIR Flex Clamp accessories.
  • Rely on the protection of CAT IV—600V, CAT III—1000 V safety ratings.
Document and share results:
  • Store data onboard or share wirelessly for improved workflow.
  • Store electrical measurements and thermal images internally, for later review.
  • Wirelessly connect to FLIR Tools or the FLIR InSite workflow management app for streamlined documentation, reporting, and information sharing.
