The FlexStream™ System is ideally suited for creating trace concentration – ppm, ppb, and pptr – mixtures. The FlexStream™ uses KIN-TEK Trace Source™ disposable, refillable and diffusion permeation tubes for over 550 Supported Chemicals. Permeation tube oven with wide temperature range controlled to 0.01 °C.
The FlexStream™ Gas Standard Generator System is composed of one or more modules, depending on application requirements.
The FlexStream™ Gas Standard Generator System provides:
· High-accuracy primary dilution mass flow rate
· Front panel color touch-screen human interface
· Automation of all calculations; key in the target concentration and the FlexStream™ sets the flow rate
· Single-oven module can create mixtures with up to 8 components
· External computer monitoring and control
· Expandable
