Learn More About Triplett Hygro-Thermometer

What is Hygro-Thermometer?

A hygro-thermometer measures relative humidity (RH) and temperature. The unit of measure for relative humidity is percent (the range is 0.0 to 100.0%). 100% relative humidity is the maximum amount of moisture that air can hold without condensation. Temperature is sensed on Extech Hygro-Thermometers by a thermistor and is displayed in °C or °F.

What is Dew Point?

Dew Point is the temperature at which water vapor condenses. It is not as common as relative humidity measurements but has applications in meteorological, chemical, and electronic assembly areas.

What is a Psychrometer?

A Psychrometer is a Hygro-Thermometer that uses Wet/Dry Bulb technology. Wet/Dry Bulb is a complex humidity-temperature measuring technology that Triplett meters simulate using an internal algorithm.
