Product overview: Fluke 28 II Ex Intrinsically Safe True RMS Digital Multimeter

Now there’s one intrinsically safe digital multimeter (DMM) you can use in IIC (gas), in Zone 1 and 2 and IIIC (dust), Zone 21 and 22. Whether you work in petroleum, chemical, or pharmaceutical environments, all the test and troubleshooting power you need is packed into the most rugged intrinsically safe (IS) DMM Fluke has ever built. The Fluke 28 II Ex is also waterproof, dust-proof and drop-proof. You’ll be equipped to handle any situation, inside and outside of hazardous zones, without compromising compliance or measurement performance.

All the measurement functions of our most popular industrial DMMs

One tool equips you with all the testing and troubleshooting power you need wherever you go––inside or outside ATEX zones 1,2,21, or 22. No need to carry different meters for different areas, or worry about crossing through an Ex-required zone with a non-Ex rated instrument.

4-1/2 digit mode for precise measurements (20,000 counts)
True-rms ac voltage and current for accurate measurement on nonlinear signals
Measures up to 1000 V and 10A AC and DC (note that Ex zones require reduced measurements)
Low pass filter ensures accurate voltage and frequency measurements on variable speed motor drives (VSDs)
Frequency to 200 kHz and % duty cycle to help you diagnose VSDs and switching power supplies
Resistance, continuity and diode test
10,000 μF capacitance range for components and motor caps
Conductance measurements for high resistance or leakage tests
Min/Max-Average and Peak capture to record transients and variations automatically
Relative mode to remove test lead interference on resistance measurements
Auto and manual ranging for maximum flexibility
Input Alert protects you by chirping and flashing “Lead when leads are plugged into the wrong inputs

Easy to use

Important extras keep you productive all day long in less than optimal conditions.

Backlit keypad buttons provide extra visibility in poorly lit areas, even when you’re wearing full PPE
Large display digits and 2-level bright white backlight also increases visibility
Long battery life – 400 hours typical without backlight (Alkaline)
Optional magnetic hanger for easy setup and viewing while freeing your hands for other tasks

Easy to service in the field

Access to the separate battery compartment makes it easy to change batteries or fuses without jeopardizing instrument calibration.
