Environics ® Product Data Series 2000U Ultra High Purity Computerized Calibration System Purity of calibration gases is assured with the Series 2000. Manufactured with metalsealed MFC’s and orbitally welded joints, the system has minimal dead volume and maintains a low leak rate to prevent atmospheric contamination of gas calibration standards. The Environics® Series Ultra High Purity Computerized Calibration System automatically blends and/or dilutes gases to generate precise gas calibration standards, to create gaseous atmospheres, or to produce gas mixes for analytical research or production purposes. The Series 2000 possesses the capacity to create blends that contain up to eight (8) individual component gases in a balance gas. The concentration of each component may be independently varied in response to user commands. The instrument’s mass flow controllers are factory calibrated using a primary flow standard traceable to the United State’s National Institute of Standards and Technology (NIST). The calibration data consists of an eleven-point comparison of commanded versus actual flow with linear interpolation between points. PRODUCT FEATURES AND BENEFITS SOFTWARE Mixes up to eight (8) gases automatically. The Series 2000 has six primary routines. Generates a wide range of complex gas standards. Concentration Mode: User enters target output gas concentration for the span gas. The actual concentration is displayed during mixing. Minimize inventory gas cylinders 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. Accuracy: 1% of reading All plumbing is orbitally welded to adhere to strict leak specifications. Components have minimal dead volume and low leak rates (2 x 10-9 atm cc/ sec He). High capacity memory permits storage and recall of up to 200 multi-component “recipes” saving time and reducing errors. Automatic Sequencer: Permits unattended automatic operation of the instrument on a programmable seven-day schedule. Twenty-five (25) by eighty (80) character display permits viewing of data worksheet form. Purge Mode: Purge component gas circuits and mixing zone. Status (Optional): Allows user to remotely activate different modes of the system and also activate external devices Optional RS-232 Serial Data Interface permits remote operation and complete integration with a computer-controlled system.
