Environmental Test Chamber.

Environmental / Climatic test chamber used to test effects that climatic changes have on products placed within environmental chambers. These chambers evaluates product quality, identifies weaknesses, etc.  High temperature, low temperature and humidity testing conditions can be done in single unit either manually / programmed with cyclic operation conditions.

Standard sizes                     :             600mm x 600mm x 600mm
                                                                750mm x 750mm x 750mm
                                                               1000mm x 1000mm x 1000mm

Temperature ranges            :               -10 to +100°C / -40 to +100°C / -70 to +100°C / -70°C to +150°C
Humidity range                       :               40% to 98% @ 30°C to 80°C.
