A Thermohygrometer or thermohygro meter is a device used to measure both temperature and relative humidity in the air. It is commonly used in indoor environments such as homes, offices, and laboratories to monitor temperature and humidity levels for comfort and safety. Thermohygrometer consists of a sensor that measures both temperature and humidity, and a display that shows the readings. The sensor is often combined with a probe that can be placed in different locations to measure temperature and humidity in different areas.
The temperature measurement is usually displayed in degrees Celsius or Fahrenheit, while the humidity measurement is displayed as a percentage relative to the maximum amount of moisture that the air can hold at the current temperature. This is known as the relative humidity.
