Fluke 28 II Ex Intrinsically Safe True RMS Digital Multimeter

Fluke 28 II Ex Intrinsically Safe True RMS Digital Multimeter

Product Introduction

The Fluke 28 II Ex is an intrinsically safe digital multimeter (DMM) engineered for reliable testing in hazardous environments, including petroleum, chemical, and pharmaceutical industries. Combining rugged durability with advanced functionality, this IP67-rated meter is drop-proof, waterproof, and dust-proof, making it suitable for ATEX Zones 1 and 2. It delivers high-end troubleshooting capabilities with 4-1/2 digit precision (20,000 counts), true-RMS measurements, and specialized features for variable speed drive (VSD) diagnostics, all while meeting strict intrinsic safety certifications (Ex ia IIC T4 Gb / Ex ia I Ma).

Product Features

Intrinsically Safe Design for Hazardous Areas:

Certified for ATEX Zones 1/2, IECEx Ex ia IIC T4 Gb, and Ex ia I Ma for use in explosive gas and mining environments.

Eliminates the need for separate non-Ex meters when crossing hazardous zones.

Precision Measurement Capabilities:

4-1/2 digit mode (20,000 counts) for accurate readings in industrial settings.

True-RMS AC voltage/current for linear/nonlinear signal analysis (up to 1000V/10A AC/DC).

Specialized Industrial Functions:

Low-pass filter for accurate VSD voltage/frequency measurements.

Frequency (up to 200 kHz) and duty cycle (%) for switching power supply diagnostics.

10,000 μF capacitance range for motor capacitors and components.

Comprehensive Testing Modes:

Resistance, continuity, diode test, and conductance for leakage/high-resistance checks.

Min/Max-Average and Peak capture for transient recording.

Relative mode to eliminate test lead resistance interference.

Rugged & User-Friendly Design:

IP67 rating: Dust-tight and waterproof (submersible up to 1m).

Drop-proof up to 3 meters for durability in harsh conditions.

Backlit keypad and 2-level bright LCD for visibility in low-light or PPE environments.

Practical Field Features:

400-hour battery life (alkaline, without backlight).

Optional magnetic hanger for hands-free operation.

Separate battery/fuse compartment for field servicing without recalibration.

Safety & Alert Systems:

Input Alert: Chirps and flashes when leads are plugged into incorrect inputs.

Auto/manual ranging for flexible measurements in diverse scenarios.
