KIN-TEK FlexStream Gas Standards Generator

FlexStream™ Gas Standards Generator

KIN-TEK's new FlexStream™ automated gas standards generating instrument [brochure] offers flexibility for creating precision gas mixtures. Mixtures are produced by diluting the emission from permeation tubes, or diffusion tubes, with an inert diluent, typically nitrogen or zero air. The FlexStream™ is ideally suited for creating trace concentration - ppm, ppb, and pptr - mixtures. An internal microprocessor sets the operating mode and adjusts dilution flows to achieve desired concentrations.

The FlexStream™ is built around a stand-alone Permeation Tube Unit. This unit provides a temperature-controlled permeation tube oven, front panel touch-screen interface and dilution flow controls. The FlexStream™ is easily transportable and can integrate with other KIN-TEK gas mixing systems (contact the Factory). Mixtures containing up to 8 components are possible. The FlexStream™ can use all KIN-TEK Trace Source™ permeation and diffusion tubes.

The FlexStream™ can also be controlled remotely by a PC or process computer using ModBus® connectivity.
