Certified for use in Class I, Division 1 environments, and Zones 1 and 2, it’s the obvious choice for workers who move between “safe” and hazardous zones, eliminating the need for multiple meters or risking accidental entry with unapproved instruments. With the 28 II EX, you have the freedom to focus on troubleshooting and problem-solving, not equipment restrictions.

Engineered for Total Ruggedness and Durability

The world outside a laboratory is often physically demanding, and nowhere is this more evident than in hazardous process environments. With heavy gloves, bulky personal protective equipment (PPE), frequent exposure to temperature extremes, and the ever-present risk of accidental drops, test equipment cannot be fragile. The Fluke 28 II EX rises above all others, thanks to a design philosophy that prioritizes unparalleled toughness and environmental resilience. Its case is completely sealed and IP67 rated—making it impervious to dust and resistant to submersion in water up to 1 meter. The meter is also drop-proof up to 10 feet (3 meters) with its holster—test results remain reliable even after rough handling or accidental falls.

Every aspect of the multimeter’s physical design is aimed at real-world survival. The built-in rubber holster offers extra protection, while a reversible cover can be slid over the display during transportation, securing the most vulnerable component from scratches or direct impact. This multimeter is not just suited to pristine control rooms but is at home on hot or freezing refinery decks, inside chemical tanks, around wet docks, or in any industrial maintenance setting where conditions are extreme and unpredictably harsh. From its wide operating temperature range (–15°C to +55°C; storage down to –40°C) to its robust, impact-resistant construction, the 28 II EX endures and performs where others fail.

The thoughtful engineering extends to ease-of-servicing: technicians can access a separate battery compartment in the field, enabling quick battery changes or fuse replacements without dismantling the casing or jeopardizing factory calibration. With a battery life of 400 hours on standard AAA cells (without backlight), downtime is minimized—a crucial asset for operations that must run continuously and efficiently.

Complete Measurement Functions for Broad Utility

In the high-stakes world of hazardous industry, efficiency is as vital as safety. The Fluke 28 II EX Intrinsically Safe Digital Multimeter is not only built to withstand extreme conditions—it is equipped with one of the broadest and most advanced suites of measurement functions in Fluke’s portfolio, drawing upon the best features of the company’s most popular industrial DMMs. Whether you’re tracking down voltage drops on a remote pumping station, diagnosing variable frequency drives on a crowded refinery floor, or verifying control signals amidst complex wiring, the 28 II EX is the only tool you’ll ever need.

A 4-1/2 digit mode delivers up to 20,000 count resolution for fine, detailed readings, ensuring no anomaly goes unnoticed. True-RMS AC voltage and current measurement means even nonlinear loads, such as those encountered with VSDs (variable speed drives) or modern switching power supplies, can be accurately analyzed. Voltage and current measurements reach up to 1000 V and 10 A in both AC and DC modes, and though certain Ex zones require reduced measurement levels for safety, the multimeter remains extremely capable when used outside of risky atmospheres. The integrated low-pass filter delivers stable, accurate readings of VSD outputs and noisy signals by filtering out high-frequency interference—a necessity for troubleshooting sophisticated industrial electronics.

Additional functions broaden the meter’s versatility even more: measure resistance up to 50 MΩ, check continuity with audible alerts, test diodes, and determine capacitance up to 10,000 μF, all with exceptional precision. High-resistance conductance tests enable fine leakage detection—critical for safety and preventive maintenance. Frequency can be gauged up to 200 kHz, with detailed duty cycle percentages assisting diagnosis of switching circuits or pulse-based controls. The integrated Min/Max-Average and Peak capture features automatically record signal variances and capture events as brief as 250 microseconds—offering unmatched insight into transient events and line disturbances.

Purpose-Built for Real-World Productivity
