Why Use a Thermohygrometer?

Thermohygrometers are the most common type of humidity sensor and you’ll find them in handheld units and transmitters. They commonly display temperature and humidity simultaneously and have a response rate of about four seconds. Their sensors read resistance or capacitance. Typical applications include:
