DG2

Dew-Point Generator

The DG2 has two stages of gas-fl ow mixing which allow
it to generate dew points down to -75°Cdp (-103°Fdp).
The great strengths of the DG2 are its ease of use and
its fl exibility in manually generating an accurate target
dew point by fi ne tuning the gas mix via its fl ow metering
valves. Infi nite mixing is achievable within its working
range.

DG3

Dew-Point Generator

The DG3 is our entry-level, single-stage mixing humidity
generator. It is operated by manually mixing the two
gas streams using fl ow control valves. The DG3 provides
fl ows up to 5 Nl/min (10.6 scfh) and generates dew points
ranging from -40 to +20°Cdp (-40 to +68°Fdp). Infi nite
mixing is achievable within its working range.
