Frequently Asked Questions

A gas tank will have a changing water vapor concentration based on the current temperature. Because of this, there is not an option to buy a tank that would have a known and constant water vapor concentration. The LI-610 provides a stream of known dew point for calibration purposes.

A chilled mirror hygrometer measures the current dew point of a gas, whereas the LI-610 Dew Point Generator produces a stream of gas with a precisely controlled dew point.
