Functional and Structural Features Overview

Basic Function

The Rubber and Plastic Material Resistivity Testing Platform, when combined with a four-probe instrument, forms a complete testing system. It is a multifunctional integrated measurement device designed for measuring the resistivity/sheet resistance of semiconductive rubber-plastic materials or thin films using the parallel four-knife method and four-terminal measurement principle (hereinafter referred to as the testing platform).It complies with the national standard for rubber and plastic industry:

GB/T 3048.3-94《Electrical Performance Test Methods for Electric Cables and Wires – Volume Resistivity Test for Semiconductive Rubber and Plastic Materials》.

Basic Composition

The testing platform consists of the following components: Sample box、Test electrode assembly、Lifting platform、Support frame、Connection cables.

Compatibility and Supporting Equipment

This testing platform is compatible with all desktop four-probe testing instruments from the same manufacturer. It is also compatible with most four-probe resistivity/sheet resistance testing instruments available from other domestic manufacturers.

Key Advantages

The electrode assembly adopts a fast constant-pressure manual lifting mechanism, offering excellent stability, compact structure, and easy operation.

The sample box is made of high-temperature resistant, corrosion-resistant, and highly insulating materials, and is equipped with conductive terminals. This design allows cleaned standard samples to be conveniently clamped and then subjected to drying, aging, testing, and transportation processes, while preventing contamination caused by direct hand contact, thereby improving measurement accuracy.
