Fluke 28 II Ex Intrinsically Safe True RMS Digital Multimeter:-

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).

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.
