Warmbier Wrist Band & Shoe Tester :PGT120

  • The Personnel Grounding Tester PGT 120 is a wrist strap and footwear tester for access control of ESD protected areas (EPA-s)
  • The test result is indicated with audible and visual signals. A relay with a dry contact provides the connection to a door opening system
  • Power supply: Internal battery or external power supply unit
  • Wrist strap, right and left shoe testing is simultaneously possible by separate measuring circuits
  • In combination with a barrier gate, the footwear measurement can be performed in series without pressing a button (hands-free mode).
  • Separate measurement of left and right shoe
  • Lower limit disabling is possible
  • The unit can be used on bench tops or as a wall mounted unit (Wall mounting requires an additional wall mounting plate)
  • Adjustable limits through dip switches
