Series 6103

Ozone Transfer Standard / Multi-Gas Calibrator

The Environics® Series 6103 Ozone Transfer Standard / Multi-Gas Calibrator is a computer controlled, state-of-the-art instrument for dynamic multi-point calibration of ambient air analyzers.

The Series 6103 automatically performs zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO,O3, hydrocarbons and other gases of interest. The 6103 meets or exceeds all U.S. Environmental Protection Agency requirements.

The Series 6103 consists of a single chassis supporting up to 3 thermal mass flow controllers, an ozone generation module, photometer, glass output manifold, mixing chamber, a reaction chamber for gas phase titration, and control electronics.

Commands are entered from the front panel and displayed on a backlit 4 line by 20 character liquid crystal display. The instrument may also be remotely operated using contact closures or the RS-232 serial data interface (RS-232-Ethernet Adapter optional), both are standard in the Series 6103. LEADS compatibility allows seamless integration of Environics calibrators into your existing collection system.  LEADS is a commercial system for collecting, integrating, and processing meteorological, air quality, and water quality data.

The 6103 comes standard with two mass flow controllers, but a third can be added to support a larger range of dilutions. The mass flow controllers are calibrated to a NIST (National Institute of Standards and Technology) traceable primary standard. The calibration data consists of a comparison of desired versus actual flow over the full dynamic range of the instrument with linear interpolation between points. Calibration data is stored in non-volatile memory and may be updated by the user with a suitable standard.

The internal ultra-violet (UV) based ozone generator is temperature controlled and includes a precision photo-optical feedback circuit to compensate for lamp aging effects providing stable ozone generation. The ozone generator is factory calibrated using a NIST traceable photometer standard.

  • User-friendly interactive software with plain language prompts is simple to use, reducing technician training time and virtually eliminating error.
  • Automatic calculation of dilution and span gas flows based on commanded concentration eliminates the need for manual computation and allows rapid transition from point to point.
  • Internally-stored mass flow controller calibration data improves accuracy by as much as a factor of ten and simplifies field recalibration. Mass flow controllers are factory calibrated at 11 points.
  • Internally-stored ozone generator calibration data insures linear, repeatable ozone generation without photometer control. Ozone generator performance meets U.S. EPA criteria for ozone transfer standards. The ozone generator is factory calibrated at 3 points (up to 11 points are available).
  • Ozone generator pressure compensation ensures repeatable and stable ozone generation at pressures other than the original calibration pressure. This is only important when the system is being used without the photometer closed-loop control.
  • The internal photometer measures the actual amount of ozone generated, and corrects for errors, using closed-loop PID control.
  • The photometer allows an external source of ozone to be analyzed and displayed on the screen. The external ozone is connector to a separate sample port, allowing for simultaneous gas blending while monitoring the external ozone source.
  • An automated leak test function is available to determine if the system has any internal leaks. Leaks are detected based on pressure decay.
  • Concentration mode: In response to software prompting, user selects gas port, span (cylinder) gas concentration, output gas flow (total) and output gas concentration. Series 6103 automatically delivers concentrations at the total flow specified.
  • Generate Ozone: Allows user to specify, then generate a precise concentration of ozone.
  • Photometer: Allows an external source of ozone to be analyzed and displayed on the screen. Also allows user to control the ozone generator when PID control loop is enabled.
  • Gas Phase Titration: Utilizes blend and generate ozone routines to lead user through GPT using "excess NO" method.
  • Flow Mode: Allows user to manually command a desired rate of flow for each mass flow controller, individually or together, and with or without ozone.
  • Display: Allows user to monitor flow rates for each mass flow controller separately. Also provides ozone oven, pressure and photometer diagnostic information.
  • Maintain Ports: User enters the name of the span gas in the source cylinder, its concentration (ppm) and the port to which the cylinder is connected.
