Multi-Gas Calibrator AIR QUALITY MONITORING SYSTEMS The MGC101 system automatically performs zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, 03, hydrocarbons and other gases of interest. It meets all U.S. environmental protection agency requirements. SPECIFIC FEATURES: 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 any manual computation and allows rapid transition from point to point Internally-stored mass flow controller calibration data improves accuracy (factor of ten) and simplifies field recalibration Simultaneous connection from 1 to 4 gas cylinders (option for 5) Easy programming with keyboard and pop-up menu A utomatic calibration sequences programmation LCD screen (4 lines / 20 characters) Multi-gas calibrator for ambient air gas analyzer calibration MAIN APPLICATIONS: Air quality monitoring stations and mobile laboratories for manual, automatic or remote calibration Used as a reference calibrator in central station Test of analyzers: Automatic zero, precision, span, multi-point calibration and gas phase titration (GPT)

AIR QUALITY MONITORING SYSTEMS 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...
