PRODUCT DESCRIPTION
The TH-11 is a wet and dry bulb thermometer for observing air temperature and relative humidity: the dry bulb reads air temperature, the wet bulb reads the evaporative-cooling temperature, and relative humidity is taken from the pair using psychrometric tables.
It is the classic meteorological instrument for humidity observation — simple, direct and requiring no power.
