FLIR IM75-2 vs Fluke 1587 FC: Which Insulation Multimeter Excels for You?

Summary

The FLIR IM75-2 and Fluke 1587 FC are cutting-edge insulation multimeters, seamlessly integrating advanced megohmmeter functionality with True-RMS multimeter precision for electrical testing in Houston’s demanding industrial environments, such as refineries, manufacturing plants, and coating inspection facilities.

•FLIR IM75-2: Designed for sophisticated diagnostics, this multimeter delivers insulation resistance testing from 4 MΩ to 20 GΩ at up to 1 kV, featuring specialized modes like Polarization Index (PI), Dielectric Absorption Ratio (DAR), and Earth Bond Resistance. Its Bluetooth METERLiNK® integration enables real-time data sharing with mobile devices, while an IP54 rating, 3-meter drop resistance, LED worklights, and a multi-color LED compare mode ensure unmatched usability for coating inspections, motor diagnostics, and complex electrical testing in Houston’s industrial sector.
•Fluke 1587 FC: A reliable industry standard for standard insulation and multimeter tasks, this model offers robust insulation resistance testing and True-RMS measurements, enhanced by Fluke Connect® app integration for wireless data logging. While it lacks the FLIR’s advanced diagnostic modes and usability features like built-in lighting, its rugged construction, CAT IV 600 V / CAT III 1000 V safety ratings, and trusted reputation make it ideal for routine electrical testing on Houston’s job sites, including HVAC and electrical maintenance.

M-Testco provides NIST-traceable certification for both models at our Houston facility, ensuring compliance and precision for your critical testing needs.
