Fluke 28II Ex Intrinsically Safe True RMS Digital Multimeter

Now there's an intrinsically safe digital multimeter (DMM) you can use in a variety of hazardous environments.Fluke introduces a rugged, intrinsically safe (IS) digital multimeter: drop-proof, waterproof, and dust-proof (IP67); and whether you're working in petroleum, chemical, or pharmaceutical environments, the 28 II Ex delivers the precise testing and troubleshooting you need.28 II Ex 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) Category I, Zone 1, Groups A, B, C, D T4 Category I, Zone 1, AEx ia IIC T4 Ex ia IIC T4
PCEC (China) Ex ia IIC T4 Gb
Simtars (Australia) Ex ia I Ma
IEx (Brazil) Ex ia IIC T4 Gb

All the measurement capabilities of our popular industrial digital multimeters (DMMs)

No matter where you are (inside or outside of ATEX Zone 1 or Zone 2), you can get the testing and troubleshooting capabilities you need with just one tool. There's no need to carry different instruments for different zones, and no need to worry about carrying non-explosion-proof instruments through zones that require explosion-proofing.

• 4-1/2 bit mode for precise measurements (20,000 counts)
• True RMS AC voltage and current for accurate measurement of non-linear signals
• Measures up to 1000 V and 10 A AC and DC currents (note that Ex zones require fewer measurements)
• Low-pass filter ensures accurate voltage and frequency measurements on variable speed motor drives (VSDs)
• Up to 200 kHz frequency and duty cycle to help you diagnose VSDs and switching power supplies
• Resistance, on-off and diode testing
• 10000 μF capacity range for assemblies and motor covers
• High resistance or leakage testing using the conductivity measurement principle
• Min/Max - average and peak capture with automatic recording of transients and variations
• Relative mode eliminates test lead interference in resistance measurements
• Manual and automatic range selection for maximum flexibility
• If a wire is plugged into the wrong input, the Input Alert alarm will beep and flash "Lead" for your protection.

simple and easy to use

Important additional features allow you to remain productive throughout the day in less than ideal conditions.

• Backlit keypad buttons improve visibility in poorly lit areas, even when you're wearing full personal protection gear
• Large display digits and 2-stage bright white backlighting also improve visibility
• Long battery life - typically 400 hours without backlight (alkaline)
• The optional magnetic hook is both easy to set up and easy to read, leaving your hands free for other tasks.

Easy to maintain in the field

Access to a separate battery compartment allows for easy battery or fuse replacement without interfering with instrument calibration.
