Hanstar model 385 -SURFACE RESISTIVITY TESTERThe first pocket resistivity Meter, with Specifications ranging from 10³ Ohms per square to 10¹² Ohms per square, with accuracy ± 1/2 Decade.
The meter measures both surface resistivity and resistance to ground. To measure surface resistivity, ¬simply place the meter on the surface of the material that requires measuring, and press the green test button. The meter will then light the appropriate LED from 10³ ~ 10¹²0hms per square or insulative. To measure resistance to ground, repeat this process and insert the earth leakage lead in the earth socket attaching the croc clip to your ground point.
The meter uses correctly spaced parallel bars for sensing its measurements and operates with a 9 volt battery giving over 40 hours of testing time.
