The Environics® Series 6103 Ozone Transfer Standard / Multi-Gas Calibrator is a computer controlled, state-of-the-art instrument for dynamic calibration of ambient air analyzers. The Series 6103 automatically performs zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, 03, 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 2 thermal mass flow controllers, an ozone generation module, photometer, glass output manifold, mixing chamber, a reaction chamber for gas phase titration, and control electronics.      
      
Series 6103 Picture 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, both are standard in the Series 6103.      
      
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.
