Ring probe for measuring the surface resistance

This ring probe is a professional measuring tool designed for precision surface resistance testing in accordance with international IEC standards. It is used to verify that flat surfaces and packaging materials meet the requirements for ESD protection, delivering accurate and repeatable results on critical areas where high measurement precision is essential. When used together with a compatible measuring electrode, it provides optimal accuracy and full compliance with IEC 61340-5-1. The ring probe is supplied in a conductive protective case for safe storage and transport, and the set includes a stainless-steel reference plate and an insulating plate to ensure proper test setup. This makes the equipment complete and ready for professional use straight out of the box.
