FLUKE-28II TRMS Rugged IP67 Digital Multimeter

Built for Harsh Sites, Accurate in Noisy Panels

The Fluke 28 II TRMS Digital Multimeter delivers lab-grade accuracy in tough field conditions. With IP67 sealing, a 3 m drop rating, and CAT IV 600 V/CAT III 1000 V safety, it keeps you productive around VFDs (Variable Frequency Drives), switchgear, and outdoor installations. A dedicated low-pass filter and True-RMS measurements ensure stability on electrically noisy signals, while a built-in thermometer reduces the tools you carry.

Key Benefits & Features

• Ruggedized IP67 design: Fully sealed (waterproof and dustproof) and drop tested to 3 m (10 ft) for reliable use in harsh industrial environments.
• True-RMS with VFD low-pass filter: Get accurate voltage and current readings on non-linear loads and adjustable-speed motor drives.
• Wide measurement ranges: Measure up to 1000 V AC/DC, 10 A continuous (20 A for 30 s), resistance to 50 MOhm, capacitance up to 9999 uF, and frequency to 199.99 kHz.
• Thermometer built in: Conveniently log temperature from -200 C to +1090 C with the included Type-K probe without carrying a separate instrument.
• Long runtime and visibility: Up to 800 hours on three AA batteries, with large digits and a two-level bright white backlight for dark panels.

Ideal Use Cases

• Industrial maintenance on VFD-driven motors and pumps
• Electrical troubleshooting in plants, mining (MSHA approved), and utilities
• Field service in outdoor or wet locations
• Commissioning and acceptance testing for control panels
