計算機氣體稀釋系統

   的詳細介紹
2020型計算機氣體稀釋系統,自動產生**的氣體標準為快速多點校準.
The Environics® Series 2020 Computerized Gas Dilution System automatically generates precise gas standards for rapid multi-point and multi-scale calibrations. The Series 2020 precisely dilutes high concentration Protocol-1 or certified gas cylinders to an infinitely variable range of concentrations from high percents to low parts per million. The instrument meets or exceeds the performance requirements of the new United States EPA 40 CFR Part 51 Method 205 Appendix M.

The Series 2020 consists of a single chassis supporting up to six (6) mass flow controllers (standard configuration), a serpentine pre-mix zone and a zero dead-space final mixing zone. Gas wetted surfaces are Electropolished 316 stainless steel. Seals are gas-compatible elastomer. The user interface includes a back-lit 80 character by 25 line cold-cathode liquid-crystal display and membrane keypad.

The instrument's mass flow controllers are factory calibrated using a computer controlled primary flow standard traceable to the United States' 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 the points.

The Series 2020 計算機氣體稀釋系統is available in a standard 19 inch rack mountable configuration for station or van usage or a portable bench-top version.

The optional RS-232 data interface permits remote or computer operation of the instrument.

 


PRODUCT FEATURES AND BENEFITS

  • Broad range of dilution ratios (1:1 - 10,000:1, standard) allows the user to significantly reduce the number of gas cylinders needed to perform compliance tests.
  • Broad dilution ratio capability allows calibration of most analyzer ranges from one cylinder of each gas specie significantly reducing gas costs, transport and handling labor.
  • 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 transition from point to point and scale to scale.
  • Internally-stored mass flow controller calibration data improves accuracy.
  • High capacity memory permits storage and recall of up to 200 calibration "recipes" saving time and reducing errors.
  • 25 line by eighty 80 character display permits viewing of data in worksheet form.
  • RS-232 Serial Data Interface permits remote operation and complete integration with a computer-controlled system.
  • Automatically calculates K-factors using system gas library.

SOFTWARE

The Series 2020 has six primary routines
  • Concentration Mode: User enters Target Output Gas Concentration (PPM or %) for the span gas. The actual concentration is displayed during mixing.
  • Flow Mode: User enters Target Flow Rate (cc's per minute) for the span gas and dilution gas. Actual flow rates are displayed after mixing is initiated.
  • Maintain Ports: User enters the name of the span gas in the source cylinder, its concentration (PPM or %) and the port to which it is connected.
  • Status Output: (Optional) Allows user to remotely activate different modes of the system and also activate external devices.
  • Automatic Sequencer: Permits unattended automatic operation of the instrument on a programmable seven-day schedule.
  • Divider Mode: Allows the user to operate the instrument as a computerized ten (10) step gas divider.
