INTRODUCTION
MEWOI-HZR100 is an ultra wide-range,battery operated, portable instrument for measuring Surface Resistivity of virtually any flat surface confoming to ASTM D-257 standard by using recommended parallel bar sensing probe. In the circuit industry,products such as packaging materials, ESD shielding bags, work bench surfaces,static dissipative table and floor mats,conveyor belts,etc,have resistance 118alues which need to confom to stringent specifications. Moreover, these 118alues are expected to fall with in specified limits. The Surface Resitivity Meter can play a vital role in monitoring and checking the resistivity characterstic of the above items. It also has unique additional feature of surface-to-ground measurement capability wherein the resistivity differential between any surface and any chosen ground can be determined. The surface resistivity is conveniently indicated by a row of LEDs covering a total of 10 decades from 103 to 1012 ohms per square. |
