FLUKE 28 II Ex Intrinsically Safe Digital Multimeter

FLUKE products designed to intrinsic safety standards - A protection method employed in potentially explosive atmospheres, intrinsically safe devices are designed to be unable to release sufficient energy, by either thermal or electrical means, to cause ignition of flammable material (gas or dust/particulates).

Potentially explosive atmospheres can be found in a variety of manufacturing environments from chemical or pharmaceutical processing, to oil refineries, or any environment where flammable material (gas or dust/particulates) are present.  FLUKE’s intrinsically safe test tools can be used to help you perform maintenance and calibration tasks in potentially explosive and hazardous classified areas.

FLUKE 28 II equips you with all the testing and troubleshooting power you need wherever you go (inside or outside ATEX zones 1,2,21, or 22).   No need to carry different meters for different areas, or worry about crossing through an Ex-required zone with a non-Ex rated instrument!


FLUKE 28 II EX True-RMS Specialty Meter:

Best for: Industrial troubleshooting in explosive environments.  Solving problems on motor drives, in plant automation, power distribution and electromechanical equipment.

With advanced capabilities:

  • Safety and compliance: Designed for use in dangerous or explosive atmospheres
  • Agency approvals: IECEx Ex ia IIC T4 Gb, Ex ia IIIC T130 °C Db, I M1 Ex ia I Ma
  • Designed for industrial troubleshooting

  • A completely sealed, IP67 rated case
  • Withstands drops up to 10 ft or 3 m (with holster)
  • Dustproof per IEC60529 IP6x
  • Waterproof per IEC60529 IPx7
  • Meets IEC Overvoltage Electrical Safety Standard No. 61010-1:2001
  • Measurement Category III, 1000V, Pollution Degree 2
  • Measurement Category IV, 600V, Pollution Degree 2
  • Reversible holster for added protection of the display when not in use
  • 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
  • Optional magnetic hanger for easy setup and viewing while freeing your hands for other tasks
  • Long battery life - 400 hours typical without backlight (Alkaline)
  • Access to the separate battery compartment makes it easy to change batteries or fuses without jeopardising instrument calibration

FLUKE 28 II Key Features:

  • 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
