Overview:
These are widely used for testing various types of materials, components and equipments for their tolerance of heat, cold, dry and humidity. It is applicable for quality inspection of all types of electronic products, electrical appliances and products from communication, automobiles, plastics, metal, food, chemical, building materials, medical components and equipments and aerospace spares and components.
Further the chamber can be used for environmental tress screening(ESS) of the temperature portion of 5°C/Min ramp rate as these chambers are capable of having ramp rate of 5°C/Min and above between +80°C to minus 40°C.
