The housing for Thermometer, Hygrometer & other instruments.
Thermometer Screen is used to place the different thermometers in open environment.
There are 2 types of screens are in use. (1) The small thermometer screen (Stevenson Screen) for shielding meteorological thermometers & (2) Large thermometer screens for shielding recording recording thermographs & hygrographs in addition to thermometers. A set of four thermometers, a wet bulb thermometer, a dry bulb thermometer, a maximum thermometer, a minimum thermometer, is generally used at meteorological observatories for routine temperature and humidity measurements. These are exposed in wooden louvred thermometer screens which support the thermometers, shield them from direct radiation from outside sources and from precipitation while allowing free circulation of air around them, and prevent accidental damage. |
