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.
