I. Product Overview
This instrument is mainly used to test the insulation resistance, volume resistance, and surface resistance of insulating materials. It is a universal testing instrument. By selecting different test electrodes, it can meet and test all types of insulating materials, such as powders, sheets, films, and liquid solutions. The instrument has a wide measurement range, up to 10^18 Ω, which can almost meet the testing requirements for all insulating materials on the market.
II. Material Types:
Suitable for measuring the volume and surface resistance of insulating materials such as rubber, plastics, films, and blocks, as well as various insulating materials in powder, liquid, solid, and paste forms.
III. Applicable Customers:
Suitable for metrology institutes, third-party testing agencies, research institutions, R&D departments of manufacturing enterprises, and quality inspection users.
