Will your material build up a static charge — or safely dissipate it? For ESD packaging, cleanroom flooring, electronic housings, and antistatic films, that answer comes down to surface resistivity. Searching for a dependable surface resistivity testing lab in chennai, tamilnadu? Kiyo R&D Lab measures how easily current flows along your material’s surface, so you can classify it correctly and meet your ESD spec.
From antistatic films and ESD packaging to flooring, coatings, plastics, and textiles, our expert team delivers accurate ohms-per-square values, supporting data, and clear, audit-ready reports you can rely on.
Surface resistivity is how strongly a material resists electric current flowing along its surface. It’s measured in ohms per square (Ω/sq) — a value independent of the square’s size, which is why it can be compared across products. Electrodes are placed on the surface, a voltage is applied, and the resulting current gives the resistivity. A reliable surface resistivity testing lab in chennai, tamilnadu turns that measurement into a precise, classifiable number.
This is the property that decides whether a material is insulative, static-dissipative, or conductive — the classification your ESD packaging, flooring, or electronics spec depends on.
As a full-service surface resistivity testing lab in chennai, tamilnadu, we test films, packaging, flooring, coatings, plastics, and textiles using concentric-ring and parallel-bar electrode methods with controlled humidity conditioning.
