I.S. Multimeter for Hazardous Locations
Ex-DM 1000 Intrinsically Safe Multimeter
  • 11 functions to choose from
  • 4½ digit display plus bar indicator
  • Distinct backlighting
  • Input alert feature
  • Min/max/avg. function
  • Ruggedized design
  • Splash & dust proof
  • CAT III 1,000 Volt
Now you can carry one versatile multimeter in both classified (hazardous) locations and regular non-classified areas. The Ex-DM 1000 provides all of the commonly required functions for plant electrical maintenance in a robust package with a backlit 4½ digit display. Approved to intrinsic safety standards by Factory Mutual for use in the U.S., and ATEX certified for use in many other parts of the world, this multimeter can be directly connected to intrinsically safe loops and instruments (certain limits apply – see specification below).
