Product Introduction
The surface resistance of the shielding suit for live-line work directly determines the level of electrostatic protection for the human body in the area of high electric field intensity. After being sweated and washed, the resistance of the shielding suit will change. When it exceeds a certain value, the protective effect will decline and it is no longer allowed to be used. The national standard and IEC standard are 1000mΩ.
 
This measuring instrument is a dedicated device for measuring the surface resistance of shielding suits for live working. It is designed and manufactured in accordance with the national standard GB6568.2-2000 "Test Methods for Shielding Suits for Live Working". It can be used to check the surface resistance value of flexible surface materials such as fabrics and clothing, and is a commonly used device for live-line operation teams that need electrostatic protection operations.
 
This instrument is compatible with national standards and adopts a four-electrode structure. It measures the inter-electrode resistance by the current/voltage method based on the electrode structure.
