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 Technical Specifications Safety Rating: CAT IV 600 V, CAT III 1000 V Voltage Range: 0.1 mV to 1000 V AC/DC (True-RMS) Current Range: 0.1 uA to 10 A (20 A for 30 s) Capacitance: 1 nF to 9999 uF Frequency: 0.5 Hz to 199.99 kHz Resistance: 0.1 Ohm to 50 MOhm Display: 6000 counts (20,000-count high-resolution mode) Ingress Protection & Drop: IP67, 3 m (with holster) Operating Temp/Humidity: -15 C to +55 C, 95% RH (down to -40 C for 20 min) Power & Life: Three AA batteries, up to 800 h Included: TL75 test leads, AC175 alligator clips, 80BK-A Type-K thermocouple Make every reading count with Fluke Equip your team with a meter built for industrial reality and compliant safety.
