Model MGC 101 LCD -Computerized Multi-Gas Calibrator
The MGC101 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. 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 MGC101 ozone generator is factory calibrated using a NIST traceable ozone standard. This temperature controlled, ultra-violet (UV) based ozone generator includes a precision photo-optical feedback circuit to compensate for lamp aging effects. The MGC 101 is available in either a standard rack mount or portable configuration.
Applications
- Air quality monitoring stations and mobile laboratories for manual, automatic or remote calibration
- Used as a reference calibratore in central station.
- Test of analyzers : Automatic zero, precision, span, multi-point calibration and gas phase titration (GPT).
Main features and benefits
Exceeds all U.S. Environmental Protection Agency requirements.
- 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.
- Internally-stored ozone generator calibration data insures linear, repeatable ozone generation without photometer control. Ozone generator performance exceeds U.S. EPA criteria for ozone transfer standards.
- Ozone generator pressure compensation ensures repeatable ozone generation at a flow rate and back pressure other than that at which it was originally calibrated
- 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.
Software
- Blend: In response to software prompting, user selects gas port, span (cylinder) gas concentration, output gas flow (total) and output gas concentration. MGC 101 automatically deliveres 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.
- Manual: Allows user to manually command a desired rate of flow for each mass flow controller.
- 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.
