Wrist Strap Tester & Surface Impedance Tester



*Can be used anywhere to quickly and easily check grounding
systems for instance wrist straps and anti-electrostatic cushion and
grounding wire.
* Ensures employee safety                                                         
* Eliminates product defects caused by static electricity.               
* Touching the mat with your hand when grounding wire is
connected.  The green “Good” indicator will be on and buzzing
when you have safe grounding system.
