The FLIR IM75-2 and Fluke 1587 FC are two leading insulation multimeters that combine megohmmeter functions with True-RMS multimeter capability. Both are designed for electrical testing in industrial environments, including motors, drives, and insulation systems.

The FLIR IM75-2 stands out with advanced insulation modes (Polarization Index, Dielectric Absorption, Earth Bond Resistance), Bluetooth METERLiNK® integration, and rugged usability features like LED worklights and IP54 durability. The Fluke 1587 FC offers solid insulation and multimeter performance with Fluke Connect® app support, but lacks some of the modern usability extras found in the FLIR.

M-Testco provides NIST-traceable certification in Houston for both models to ensure accuracy and compliance.

❓ Q&A Section

Q: Which insulation multimeter offers more advanced testing modes?
A: The FLIR IM75-2 provides specialized insulation modes including Polarization Index (PI), Dielectric Absorption Ratio (DAR), and Earth Bond Resistance, making it more versatile for diagnosing insulation health. The Fluke 1587 FC provides standard insulation resistance testing without these extras.

Q: Do both support app connectivity?
A: Yes. The FLIR IM75-2 connects via METERLiNK® Bluetooth, while the Fluke 1587 FC uses Fluke Connect®. Both allow wireless data sharing, though FLIR includes more in-field usability features.

Q: Which is more rugged for industrial use?
A: Both units are CAT IV / CAT III safety rated. The Fluke 1587 FC is well regarded for durability, while the FLIR IM75-2 matches toughness with an IP54 rating, 3 m drop test certification, and built-in LED worklights for dark environments.

Q: Which model is better for coatings and advanced diagnostics?
A: The FLIR IM75-2 offers more diagnostic modes and user-friendly field features, making it the stronger choice for detailed electrical and coatings inspection workflows.

Q: Can M-Testco certify both models?
A: Yes. M-Testco provides NIST-traceable certification in Houston for both the FLIR IM75-2 and the Fluke 1587 FC.
