LI-610 Portable
Dew Point Generator

The LI-610 Portable Dew Point Generator is a rugged, portable instrument that provides a stream of gas with a precisely controlled dew point. High accuracy and stability make the LI-610 an ideal water vapor source for field or laboratory use in the environmental and biological sciences. The LI-610 is commonly used to calibrate the H2O channel of gas analyzers or other precision sensors, and provide precise control over water vapor mole fraction in environmentally regulated chambers.
