This instrument is designed to measure the volume resistivity and surface resistivity of:
Coatings, films, rubber, plastics, powder materials
Electronic components, dielectric materials, wires and cables
Anti-static products (e.g., anti-static shoes, plastics, and rubber products)
Insulation performance of raised floors in computer rooms
Electrical insulation testing of electronic devices
It uses the ring three-electrode method principle for accurate and reliable measurements.
Main unit
Standard ring three-electrode
Connection cables
Optional electrodes can be used according to standards or customer requirements to extend measurement applications.
