Programable Temperature and Humidity Chamber

Brand Name	HD		Place of Origin	China

This machine is manufactured and designed to meet the requirements of relevant standards, such as GB/T2951, UL1581, IEC540, IEC60598, etc. It is used to provide a constant temperature & humidity environment to perform a further test. Features: * Programable setting available. * The refrigeration is come from Tecumseh (France). * A big TEMI880 super induction LCD touch screen makes operation more convenient, and test graph can be shown by this screen. * P. I. D count automatically makes it can correct temperature and humidity immediately. * Controlled by a microcomputer, actions like temperature rising and humidity rising could be applied dividually. * All stainless steel structure. * The big window in the door makes your view more convenient. * Four-tiered safety system for super-cooling conditions. * RS-232 communication interface available, computer can be connected with this tester to display testing status, testing result, setting programs, operating this tester and more.
