UL498 Plug Socket Gauge

1. Application

This plug and socket test gauge is mainly used to test and inspect whether the structure and size of plugs and sockets conform to UL 498 standards. And the mainly application industries is electronics, electrical  appliances, plugs and sockets and other similar areas. 

2.Features:

 Gauge dimensions, tolerances, material, hardness, surface roughness conform to the standards requirements;

 Surface corrosion and abrasion resistance  can   resist normal contact corrosion and not embroidered  patch (the operator hand may exist in the sweat, the corrosion effect equivalent to NACL salt solution or  NH4CL salt solution corrosion);

Material hardness is more than 60HRC;Material thermal expansion coefficient is small,dimensions and tolerances is stable and reliable
