Now there's one intrinsically safe digital multimeter (DMM) you can use in a wide range of hazardous settings. 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) digital multimeter 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.
 
Extreme ruggedness
 
The Fluke 28 II Ex is one of the most rugged IS digital multimeters that  you can buy.
Completely sealed, IP67 rated case
Withstands drops of up to 10 feet or 3 meters (with holster)
IEC 61010-1: Pollution Degree 2
IEC 60529: IP67
IEC 61010-2-033: Measurement CAT III 1000 V / CAT IV 600V
 
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 the Ex hazardous zones listed above. 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 high-resolution 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 10 A 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/Avg 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 in suboptimal 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 can be used outside of Ex hazardous zones 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.
