28 II EX: the most rugged intrinsically safe multimeter in the world.

With a various range of approvals the DMM can be used globally!

Features

  • CAT III 1000V / CAT IV 600V
  • Dustproof, waterproof (IP67)
  • Measures up to 1000V / 10A (outside of the Ex-hazardous area)
  • Min/Max/Avg and Peak capture
  • Low pass filter for accurate measurements on variable speed motor drives
  • Input alert
  • 4½“ digit display (20,000 counts) with backlight

Description

Intrinsically safe and rugged

The 28 II EX carries the most important Ex-certifications and is also tested for drops of up to 3 meters. Additionally it is waterproof and dustproofed (IP67) as well. Therefor the 28 II EX DMM survives the roughest treatment in the harshest environments.

Intrinsic safety and approvals

  • ATEX, IECEx, Mining (NEC and GOST approval pending)

Extreme ruggedness

  • Completely sealed IP67 rated case
  • Waterproof
  • Dustproof
  • Meets IEC Overvoltage Electrical Safety Standard EN 61010-1:2001:CAT III 1000V and CAT IV 600V

Easy to use

  • Backlit keypadbuttons for extra visibility in poor lit areas
  • Large display digits and 2-level backlight
  • Long battery life: 400 hours typical (without backlight)

Handling benefits

  • Only one DMM is needed because of the safe and compact solution which allows safe measurement both inside and outside (max. 10A / 1000V) the Ex-hazardous area
  • A separate battery compartment makes it easy to change batteries on fuses
