Product Data Series 2000 Computerized Multi-Component Gas Mixer Environics ® GENERAL DESCRIPTION The Environics® Brand Series 2000 Computerized Multi-Component Gas Mixer automatically blends and dilutes gases to generate precise gas calibration standards, create gaseous atmospheres or produce gas mixes for analytical research or production purposes. The Series 2000 dynamically produces complex mixes containing up to, eight (8) individual component gases in a balance gas. Each component concentration may be independently varied in response to user commands. The Series 2000 can produce gas concentrations from percent levels to ppb for single or multi-point calibration of gas chromatographs, process gas analyzers, mass spectrometers, FTIR's and other gas analytic devices. Internally-stored mass flow controller calibration data improves accuracy. The Series 2000 consists of a single chassis supporting up to nine (9) mass flow controllers , a serpentine pre-mix zone and a zero dead-space final mixing zone. All gas wetted surfaces are electropolished stainless steel. Seals are gas compatible elastomers. Optional RS-232 Serial Data Interface permits remote operation and complete integration with a data station. The Series 2000 employs mass flow controllers calibrated to a NIST (National Institute of Standards and Technology) traceable primary standard. High capacity memory permits storage and recall of up to 200 multi-component "recipes", saving time and reducing errors. Twenty-five line by eighty character display permits viewing of data in worksheet form. Modular design allows user to add additional gas circuits later, reducing initial investment and protecting against obsolescence. SOFTWARE The Series 2000 has six primary routines accessible through "soft" keys, located immediately below their onscreen labels. The Series 2000 is available in either a bench top configuration or an optional 19” rack mount. Concentration Mode: User enters target output gas concentration for the span gas. The actual concentration is displayed during mixing. Flow Mode: User enters target flow rate (cc's per minute) for each component gas. Actual flow rates are displayed after mixing is initiated. Maintain Ports: User enters the name of the component gas in the source cylinder, its concentration and the port to which it is connected. Commands are entered from the front panel and displayed on a backlit twenty-five line by eighty character liquid crystal display. Calibration sequences are stored in the internal microprocessor for recall by the keypad, optional RS-232 communications or optional status interface. Automatic Sequencer: Permits unattended automatic operation of the instrument on a programmable seven-day schedule. Purge Mode: mixing zone. Status (Optional): Allows user to remotely activate different modes of the system and also activate external devices PRODUCT FEATURES AND BENEFITS Simultaneous 8 component dynamic mixing with automatic computation of component and balance gas mass flow Multi-component capability permits the user to generate a wide range of complex standards with a minimum inventory of expensive, long lead-time, multicomponent gas cylinders. Automatic calculation of dilution and span gas flows based on the concentration commanded by the user eliminates the need for manual computation and allows rapid transitition from point to point and scale to scale. Purge component gas circuits and
