FLIR CM83 600A True RMS Power Clamp Meter


product image

The FLIR CM83 is an industrial-grade power clamp meter engineered with advanced power analysis, harmonics measurements, and variable frequency drive (VFD) filtering functions to meet the needs of electrical troubleshooters. The meter features Bluetooth® technology to connect compatible mobile devices for remote viewing and sharing, and METERLiNK® technology to wirelessly embed electrical readings into radiometric infrared images on compatible FLIR thermal cameras.

FLIR CM83 Power Clamp Meter Features

VFD Mode

Accurately analyse non-sinusoidal waveforms and noisy signals in VFD-controlled equipment.

Harmonics Mode

Locate noise from different electrical draws to realign harmonics and reduce electro-mechanical equipment stress.

Phase Rotation

Analyse three-phase systems to measure power draw and verify if power is evenly balanced.

Inrush Current

Measure hard and soft start-up inrush current spikes while equipment is ramping up.

METERLiNK Compatibility

Embed electrical measurements into thermal images captured by METERLiNK-enabled FLIR IR cameras for easier documentation.

Power Factor and Active Power

Monitor power quality improvements, such as start-up realignments on three-phase equipment.

Bluetooth Connectivity

Connect to Android devices for remote diagnostics in hard-to-reach or hazardous areas. Also, upload data without the need for special cords.

Bright Dual-LED Worklights

Make your work safer/easier in poorly lit locations – especially useful when the lights are out or obstacles block your inspection targets.

Rugged & Shock-Resistant

Double-molded case design and extra thick rubber on the corners absorbs shock to enhance job-site reliability and long-haul durability.
