KIN-TEK’s new FlexStream™ modular gas standards generating system enables the creation of precision gas mixtures. The system dilutes the emission from permeation or diffusion tubes with an inert gas, typically nitrogen or zero air, to create trace concentration—ppm, ppb, and pptr—mixtures. An internal microprocessor sets the operating mode and adjusts dilution flows to achieve desired concentrations. Other features include:
- Up to six independently controlled channels, which can be permeation units or may combine permeation units with secondary dilution to expand the concentration range.
- The ability to create mixtures containing up to 48 components.
- Remote control by a PC or process computer using Modbus® connectivity.
