SL-030 is an ultra wide-range, battery operated, portable instrument for measuring Surface Resistivity of virtually any flat surface conforming 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 values which need to conform to stringent specifications, Moreover, these values are expected to fall with in specified limits. The Surface Resistivity Meter can play a vital role in monitoring and checking the resistivity characteristic of the above items.
