Suitable for carrying out different quality control tests under controlled conditions of temperature and humidity. Inner chamber consists of anodized aluminium or S.S. and outer wall of M.S. sheet duly painted. The gap of 75m.m. between the outer andinner wall is filled with special grade glass wool to prevent thermal losses. A self cooledair circulation fan is fitted to maintain uniform temperature and humidity conditions throughout. The chamber temp. range from 5°C above ambient to 60°C is controlled by "JUMO"/"EGO" GERMAN Thermostat with an accuracy of ± 1°C. Humidity is controlled through an imported HUMIDISTAT, thus controlling the desired set humidity range from atmospheric humidity to 95% +3%.
