FLIR IM75 Insulation & DMM Combo with METERLiNK®

The FLIR IM75 is both an advanced multifunction digital multimeter and premier handheld insulation tester for installation, troubleshooting and maintenance professionals. The IM75 includes several specialty insulation modes including: Polarization Index, Dielectric Absorption and Earth Bond Resistance. Insulation tests can be performed instantly, continuously and over a timed duration for in-depth assessment.

FLIR IM75 Insulation & DMM Combo Features

Combo Insulation / DMM in One

Have all the functions you need in one combination package – don’t run to the truck mid job for another meter!

Advanced Insulation Modes

Confirm your insulation resistance Insulation Resistance up to 20 GΩ, PI, DAR, Earth Bond Resistance


Multiple ranges of resistance insulation test levels available for testing electrical power lines down to telecom and low voltage systems via rotary switch: 50V, 100V, 250V, 500V, 1000V

Easy Compare

When reviewing results in Compare Mode, the dedicated Pass / Fail multi-color LED indicator makes determinations clear and visible.

DMM Built-in

True RMS DMM measurements features reliable performance and 1000V range

VFD Mode

Accurately analyze non-sinusoidal waveforms and noisy signals in VFD motors and drive controllers.

METERLiNK Compatibility

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

Bluetooth Connectivity

Connect to iOS™ and 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 (IP54, 2m Drop Test).

Ready for work

Accessories included: TA81 silicone CAT IV test leads with screw on silicone insulated alligator clips, TA50 Magnetic magnetic hanging strap, 6 x AAA batteries, User manual/CD
