FLIR Tools Mobile connects the FLIR CM83 to your compatible smartphone and tablet via Bluetooth*
METERLiNK technology wirelessly integrates electrical readings on your infrared image with FLIR Thermal Cameras
Industrial-Grade Power Clamp Meter Tackles Noisy VFD Jobs
Discover the FLIR CM83, a powerful 600A AC/DC clamp meter that offers advanced power analysis functions that add confidence when making measurements in environments where loads are using switching electronics such as variable frequency drives (VFDs) and today’s growing range of high efficiency lighting options.

Designed by the leaders in innovation at FLIR Systems, the durable power clamp gets results on tough jobs. In addition to True RMS current and voltage measurements and other standard functions, the CM83’s VFD Mode leverages a low-pass filter that ensures accuracy even when distorted waveforms exist on electronic loads (such as VFD-controlled equipment).

Power quality testing and load studies (to plan for future system-wide capacity) demands essential power measurement capabilities that set the FLIR CM83 power clamp meter apart from other test equipment.

Measure power up to 600kW as well as Total Harmonic Distortion and harmonics to the 25th harmonic helping you find problems that could cause the malfunctioning, damage or failure of important components. The fast-responding in-rush current mode enables the meter to display the highest current reading in the first 100 milliseconds after the trigger point.

This capability is ideal for getting to the root cause of nuisance tripping, spurious resets and transients.

Bluetooth Connectivity
Designed for today’s technician, the advanced FLIR CM83 connects via Bluetooth to Android smartphones and tablets using the FLIR Tools Mobile app. Now, you can monitor electrical readings on equipment in closed cabinets, with dangerous moving components, or with extreme temperatures – all from a safe distance. Plus, use the app to share diagnostic results with colleagues or customers on-site or remotely—as primary readings or within professional-looking reports you can easily create.

As part of the FLIR family, the innovative meter also communicates with METERLiNK-enabled FLIR IR cameras, helping you record electrical readings on thermal images in realtime. When you’re working on complex electrical, mechanical or pump systems for example, you want tools that can work together to gather and record all the relevant data—temperature and electrical together on one thermal image.

For your day-to-day, this not only means adding time-savings, but it also ensures accurate, coordinated documentation for PdM inspection reports.

A Brighter Idea
The FLIR CM83 continues to deliver on the value of added safety with a built in Non-Contact Voltage Detector and a built-in worklight. The non-contact voltage detector allows you to quickly and conveniently check for voltage prior to attaching the clamp meter’s test leads to the device under test—all without reaching for a separate voltage pen.

The super-bright dual-LED worklight that illuminates dark or poorly-lit work areas without the use of a flashlight. This built-in light not only frees up one hand, it adds confidence when performing visual inspections (for wear, pitting, dirt, corrosion and dust) and makes it easier to read faded labels and other markings. And for peace of mind for years to come, FLIR backs up its durable clamp meters with a limited lifetime warranty.

About the CM83
Designed rugged to handle use every day, the FLIR CM83 clamp meter offers both safety and versatility—without compromising high performance or innovation for tomorrow’s challenges. Take the CM83 on every job and it delivers with advanced meter functions including True RMS accuracy, VFD filter mode, Power Quality Mode (THD, harmonics, watts, phase rotation) AC/DC current and voltage measurement, resistance, capacitance, frequency, diode-test, and continuity check. Use the fast-responding peak hold function to capture inrush currents and transients.
The 4-digit, 4,000 count display is LED-illuminated making it bright and easy to read anywhere. Several one-button functions including data hold, min/max, and selectable auto- or manual-ranging. A relative function helps you ‘zero out’ the meter. The large 37mm jaw opening handles conductors up to 1000 MCM. The FLIR CM83 amp clamp has a CAT IV-600V, CAT III-1000V overvoltage safety rating. NIST certification is also available for this product.
