The Environics Series 9100 is a computerized ambient air calibration system designed for dynamic zero, span, and multi-point calibration of air analyzers using gases such as NO, NO₂, SO₂, CO, O₃, and hydrocarbons. It features two thermal mass flow controllers, a UV-based ozone generator with pressure compensation, and a mixing zone, all housed in a single chassis. Available in 19" rack mount or bench top configurations, it measures 19" x 7" x 23.5" for the rack mount or 17" x 7" x 23.5" for the bench top. The system includes a 25-line by 80-character backlit LCD, RS-232 remote interface, and NIST-traceable calibration for flow and ozone output, with accuracy of ±1.0% for both concentration and flow. It operates on 115 VAC or 220 VAC, requires 30 minutes to warm up, and functions within temperatures of 32°F to 122°F (0°C to 50°C).
Features include:
The Environics 9100 is the unit of choice in the Air Quality Monitoring Programs of the EPA and California Air Resource Board (CARB).

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.
** Now available with a 3rd Mass Flow Controller! **
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.
