Surface impedance tester features:
* Measurement of the surface of the object and the grounding resistance coefficient.
* For anti-static materials, insulation materials were measured.
* The use of ASTM standard D-257 method of parallel sensing electrode.
* Use high-precision integration of the OP-AMP amplifiers, light-emitting diode display.
* High sensitivity, the use of reliable.
* Small size, light weight and easy to carry.
