High And Low Temperature Test Chamber High Low Temperature Test Chamber Environmental Test Chamber
Use:
This faster temperature (& humidity) chamber enables the application of high
Stress to the specimen at a steep temperature change rate of 5℃/min. or more. A temperature change rate of 5℃ /min. or more has been achieved from －75℃⇔＋150℃, and from －18℃⇔＋158℃, thanks to the larger refrigeration systems in this mode.It consists of cooling system,heating system,controlling system,air cycle system,sensor system.
Used in equipments, chemistry,plastic rubber, electron,food,frabic,metal, aerospace industry.Simulate the temperature fast temperature changing condition,to check the product performance if changed in this condition.
