Model230气体发生器

With a flexible flow metering system to maintain a constant carrier flow through the permeation chamber, the Model 230 allows the dilution flow to be varied over a wide range, generating the spectrum of concentrations required for checking analyzer linearity. Like all Dynacalibrators, its large permeation chamber is big enough to accomodate several permeation devices, for higher output concentrations or multi-component mixtures.
