    FLIR CM74 Commercial Clamp Meter

    The FLIR CM74 Commercial Clamp Meter has practicality at its core with a narrow 35mm jaw and bright LED worklights that help you make measurements in dark, awkward places such as panels and cabinets. The device measures AC/DC current up to 600A and AC/DC voltage up to 1000V. There is also a useful input for a flexible current probe accessory which brings access to even tighter spaces and more awkward wiring.

    The moulded rubber hand grips make it easier to keep hold of the instrument when stretching to take a reading and the large LCD screen ensures that measurements are clearly visible. Its small size and slim clamps allow it to sit comfortably in your back pocket so it is easy to use and transport.

    The CM74 has all the functions needed for advanced troubleshooting including True RMS, LoZ voltage, VFD Mode, Inrush, and Smart Diode with Disable. Furthermore, AC current range can be increased from the already substantial 600A to 3000A with a TA72 or TA74 Flex Clamp Accessory. Additional features include Min/Max Hold and Auto Power Off with Disable. 

    The FLIR CM74 Commercial Clamp Meter is extremely usable and versatile. The user also benefits from FLIR's limited lifetime warranty.
