A New Apparatus for Control of Temperature and Humidity in Leaf and Small Plant Chambers

Abstract
A new electronic system for effecting feedback control of temperature from 3 to 50 °C and humidity from approximately 15 to 99 per cent is described. This system uses thermistor sensors to control, through electronic control units, the temperature of water baths which determined the temperature and humidity of the airstream passing through leaf or small plant chambers. The control has been found to be precise, and the temperature and humidity can each be reset from a separate single control knob.
