How does a hygrometer work?
Hygrometers function by the phenomenon known as evaporative cooling. When water evaporates from a surface, it becomes cold as water molecules absorb heat from the surface during the process of evaporation. Due to this effect, the wet-bulb consistently exhibits lower temperature than the dry bulb.
How often should you calibrate a hygrometer?
It is recommended that hydrometers should be calibrated when new. If they are in regular use at ambient temperature, recalibrate after one year, and then every two to three years. Hydrometers used above or below ambient temperature should be calibrated annually.
