Series 9100 Computerized Ambient Monitoring Calibration System
Available from Environics Inc.
The Series 9100 automatically performs zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, O3, hydrocarbons and other gases of interest. The Series 9100 exceeds all U.S. Environmental Protection Agency requirements.
The Series 9100 consists of a single chassis supporting up to 3 thermal mass flow controllers, an ozone generation module, a mixing zone, a reaction chamber for gas phase titration, and control electronics.
Commands are entered from the front panel and displayed on a backlit 25 line by 80 character liquid crystal display. The instrument may also be operated using contact closures or an RS-232 serial data interface.
The mass flow controllers are calibrated to a NIST (National Institute of Standards and Technology) traceable primary flow 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 the non-volatile memory and may be updated by the user with a suitable standard.
The Series 9100 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 as well as built-in pressure compensation.
The Series 9100 is available in either a standard 19" rack mount or bench top configuration.
