Features Psychrometer

A psychrometer is an instrument consisting of two ventilated thermometers, one having a wet bulb and one having a dry bulb, with a difference between their readings, caused by adiabate cooling of the wet bulb. The difference of the reading depends on the temperature of the air and moisture content in the air. Therefore the difference in reading gives the measurement of humidity in the air. The relative humidity must be calculated with these two readings or can be determined with the help of psychrometric charts.
