<Products>-Notice of ESD Chair

　TET used to handle ESD chairs manufactured by Lissner (US), but stable delivery could not be continued. So, we decided to deliver those of Gibo/Kodama Chairs. Their chairs are more reliable than the predecessor and keep enough market share. Down to class 10 cleanroom chairs are available. Every model is designed to provide the comfortable work envorpnment for long time by the best form density, seat shape variation, adjustable function to every individual. Quality exceeds that of predecessor, too.

Electro-static discharge (ESD) problems frequently occur in the environment where most advanced electron devices or instruments are handled. Typical examples include damage or degradation of electron devices in the assembling line, failure of PC, computer and other electronics instruments. Most of the reasons of frozen PC is ESD. Human is the major element that causes ESD because it moves freely. To suppress electro-static charge caused by human body, anti-static wear, shoes, floor and wrist strap are used, but chairs are also important.

Friction is the major source of static charge. Though you use anti-static wear, shoes and floor, both human body and chair are charged by sitting up and down because of friction. Some chairs may cause ESD soon after human left from it. The EMI generated by this ESD triggers failure of neighboring instruments. It is reported that this ESD occur in the gas cylinder. All Gibo/Kodama chairs do not cause this problem. Please use these chairs over the grounded conductive floor.
