Which instrument is used for measurement of humidity in air?

Hygrometer is used for measuring humidity of air. When water or ice covers the bulb of a thermometer (wet-bulb), latent heat is removed from the surface of the bulb as the water evaporates, and the wet-bulb temperature becomes lower than the air (dry-bulb) temperature. At a lower humidity, water evaporates more actively, so that the wet-bulb temperature lowerssharply. The aspirated psychrometer measures humidity by measuring the difference between the dry-bulb temperature and wet-bulb temperature.
Answer:
PCE-444 is a combination digital hygrometer and digital thermometer used to measure air temperature, relative humidity, dew point temperature and wet bulb temperature. This portable handheld pocket-sized mini thermo-hygrometer allows for the quick and easy determination of indoor ambient environmental conditions.
- Humidity measuring range: 0 ... 100% relative humidity (RH)
- Temperature measuring range: -20 ... 70°C / -4 ... 158°F
- Resolution: 0.1%, °C, °F
