Temperature Humidity Chamber BZHC-703 is a compact environmental test chamber with a true-color LED touch interface. Maximum temperatures range from 70°C to 150°C, with relative humidity levels ranging from 20% to 98% RH. It is made of stainless steel on the inside and cold-rolled steel on the outside, with a powder-coated finish, and can hold 1000 liters of volume capacity. The system includes a nichrome heating resistance wire heating system and a centrifugal blower airflow system.
