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 H2channel of gas analyzers or other precision sensors, and provide precise control over water vapor mole fraction in environmentally regulated chambers.

  • NIST certified
  • Generates stable dew points from 0 to 50 °C
  • Accuracy of ± 0.2 °C dew point
  • Completely portable and self-contained (battery or AC operated)
  • No need for gas tanks and mixing systems
  • Millivolt output of dew point temperature for data acquisition
  • External control via 0-5 V input signal
