Environics - Model Series 6100 - Computerized Multi-Gas Calibration System
The Environics Series 6100 Computerized Multi-Gas Calibration System is a computer controlled, state-of-the-art instrument for dynamic multi-point gas calibration of ambient air analyzers. The Series 6100 automatically performs zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, 03, hydrocarbons and other gases of interest. The 6100 meets all U.S. Environmental Protection Agency requirements. The Series 6100 consists of a single chassis supporting 2 thermal mass flow controllers, an ozone generation module, a mixing zone, a reaction chamber for gas phase titration, and control electronics.
PRODUCT FEATURES AND BENEFITS
- 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.
- Ozone generator pressure compensation ensures repeatable and stable ozone generation at pressures other than the original calibration pressure.
- Full, two-way RS-232 Serial Data Interface (standard) permits remote operation of the instrument including data collection, gas selection, initiation of zero, span and multi-point calibrations.
- Concentration Mode: In response to software prompting, user selects gas port, span (cylinder) gas concentration, output gas flow (total) and output gas concentration. Series 6100 automatically delivers concentrations at the total flow specified.
- Generate Ozone: Allows user to specify, then generate a precise concentration of ozone.
- 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 block temperature during generate ozone and gas phase titration routines.
- 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.
