Surface Resistance Checker Desco -19640

Specification
Used for determining if a surface is dissipative, conductive, or insulative.

Technical Information.
The Desco 19640 Surface Resistance Checker is a portable battery-powered checker fitted with built-in parallel electrodes that allow for tests of material surface resistance. This checker is designed for quick checks of surface resistance for ESD control applications in electronics manufacturing or handling environment. The Surface Resistance Checker is equipped with an automatic test voltage selector. The test voltage will switch from 10V to 100V should the measured resistance exceed 1 x 105  ohms. Two banana jacks and an electrode toggle switch allow for the connection of two external 5 pound electrodes that measure surface resistance point to point (Rtt)
