8-Cubic-Meter Walk-In Constant-Temperature/Humidity Chamber
Safe, convenient computer-based remote access; multiple levels of sensitive-data protection; convenient program access, test setup and product monitoring; Excel data export and USB transfer; control-status viewing from any networked computer. Sizes from 1 to 100 cubic units and performance configurations are customizable. The walk-in temperature/humidity chamber tests electronics and components, automotive parts and interiors, automotive glass, plastics/chemicals and aerospace materials under high/low-temperature or damp-heat conditions. Size is customizable. A version for a prominent domestic automotive-glass manufacturer powers nine front windshields, each with an approximately 1.5-square-unit heated area. Alternating +85℃, +105℃ to -45℃ and damp-heat conditions are combined with 500-hour powered load tests, totaling 6.5KW of heat load.
