Fluke 28 II EX
Intrinsically Safe True RMS Multimeter

  • 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 1000V 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/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
  • 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
  • For Non Intrinsic Model See: Fluke 28II

The Fluke 28 II EX Intrinsically Safe True RMS Multimeter is an 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.

Tested for drops of up to 3 meters (10 feet), waterproof and dustproof (IEC60529, IP67), this Fluke 28 II EX Intrinsically Safe True RMS Multimeter survives the roughest treatment in the harshest environments.

Like all Fluke DMMs, the 28II Ex delivers the accuracy and measurement performance you depend upon to succeed in your work, day after day.
