ENVIRONMENTAL CHAMBERS
The walk-in environmental test room is composed of the
thermal wallboard by means of pu foaming. It is easy to
disassemble & transport. According to the environmental
conditions that customers required, the test machine may
be used as the burning room, thermostat room and
thermostat-humidistat room if it is equipped with the
accurate control system of microcomputer for test room
have two kinds to be selected: one is the stainless steel and
the other one is the sheet baked by paintings.
