Fluke 28 II | IP67 Rugged True-RMS Industrial Multimeter for VFDs

Technicians working around motors and industrial drives often need both electrical accuracy and mechanical durability. The Fluke 28 II Rugged True-RMS Digital Multimeter addresses both requirements with IP67 sealing, True-RMS measurement and a selectable low-pass filter for electrically noisy drive systems.

It measures AC/DC voltage up to 1000 V and current up to 10 A, while a 20,000-count high-resolution mode supports finer measurements. Temperature, resistance, capacitance, frequency and continuity functions allow one meter to cover a broad range of plant-maintenance tasks. The enclosure is designed to withstand a 3 m drop and challenging moisture, dust and humidity conditions. Compared with the 27 II, the 28 II adds the measurement capabilities needed for non-linear loads and adjustable-speed motor drives, making it the more versatile rugged choice for modern industrial electrical systems.

Harsh-Environment True-RMS Selection Guide

Select the 28 II when you need the rugged construction of the 27 II plus True-RMS measurement, temperature and a low-pass filter for VFD work. If you need certified intrinsically safe operation, move to the 28 II Ex.

Market Relevance

The Fluke 28 II suits Pakistani cement plants, steel mills, textile factories, utilities, process plants, and outdoor industrial maintenance teams where dust, moisture, and motor drives are common. Buy the Fluke 28 II from Kamadi Pakistan for rugged True-RMS industrial troubleshooting.
