Application<\/h3>\n\n\n\n

The constant temperature and humidity test chamber adopts high-stability platinum PT-100 temperature measuring resistors, equipped with Chinese & English LCD touch screen and multiple sets of PID control functions. It is fitted with RS-232C\/485C computer communication interface for upper computer control. The equipment is capable of simulating various environmental conditions including high temperature & high humidity, high temperature & low humidity, low temperature & high humidity, single high temperature and single low temperature. Meanwhile, it is equipped with user-friendly, high-precision programming control and fixed-point control system to deliver excellent test performance.<\/p>\n\n\n\n
