Now there's an intrinsically safe digital multimeter (DMM) you can
use in a wide range of hazardous settings. Whether you work in
petroleum, chemical, or pharmaceutical environments, the 28 II Ex
gives high-end test and troubleshooting power you need is packed
into the most rugged intrinsically safe (IS) DMM Fluke has ever
built: drop-proof, waterproof, dust-proof (IP67). The 28 II Ex
meets the following certifications:
IECEx (International) - Ex ia IIC T4 Gb
- Ex ia I Ma
|  |
ATEX (Europe) - II 2G Ex ia IIC T4 Gb
- I M1 Ex ia I Ma
|  |
NEC / CEC (North America) - Class I, Division 1, Groups A,B,C,D T4
- Class I, Zone 1, AEx ia IIC T4
- Ex ia IIC T4

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 or 2,. 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.
