The Environics® Series 6123 Ozone Transfer Standard with Photometer is the ideal system for those looking for a standard for ozone monitoring and reporting programs. A sister unit to the S6103, the S6123 focuses on automatically performs zero, precision, span and multi-point calibrations using O3.

The S6103 is required if you wish to performs zero, precision, span and multi-point calibrations using O3 but also NO, NO2, SO2, CO, hydrocarbons and other gases of interest.

The 6123 meets or exceeds all U.S. Environmental Protection Agency requirements for a level 3 bench or transfer standard. It is exclusively for use with the internal ozone generator. For applications that require monitoring of external ozone sources, the Series 6103 or 6113 are required.

The Series 6123 consists of a single chassis supporting one thermal mass flow controller (sized per customer requirements), an ozone generation module, photometer, inline static mixer, and control electronics. There are no consumables making maintenance simple.

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 6123. RS-232-Ethernet adapter option also available.

The 6123 comes standard with one mass flow controllers 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.
