Extract

Details are given of a cabinet, with a working space of 9 cu. ft., affording temperatures constant to within ± 0·5°C. over the range 5–25°C. and relative humidities constant to within ±2·5 per cent, over the range 40·85 per cent. The apparatus has electrically operated automatic controls. The only maintenance required is two-weekly renewal of the wet-bulb wicks and filling of the distilled-water reservoirs. Most of the construction was carried out in the laboratory. The cost of the cabinet and control equipment was approximately £170.
