Standard Applications of Gas Flow Instruments

Zero Air Generator

S7000
Zero Air Generator is suitable for use as: a zero reference calibration gas, ultra-pure combustion air for flame ionization detector, and service air for pneumatically operated valves.

Calibrators for ambient air analyzers

S6100, 6103, 9100
Dynamic calibration of ambient air analyzers. The systems automatically performs zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, 03, hydrocarbons and other gases of interest. The systems meet all U.S. Environmental Protection Agency requirements.

Calibrators for CEM's

S2020 or S4040
Automatically generates precise gas standards for rapid multi-point and multi-scale calibration of Continuous Emissions Monitors (CEM's). The instrument meets or exceeds the performance requirements of the United States EPA 40 CFR Part 51 Method 205 Appendix M.

Preparation of calibration stands for VOC's

S2014
The system is designed for the preparation of calibration standards used for VOC (Volatile Organic Compounds) monitoring programs. It can dynamically produce ppb level standards from ppm level cylinder gases.

Preparation of calibration stands for Gas Chromatography and Mass Spectrometry

S2014, S4040
The system is designed for the preparation of calibration standards used for Gas Chromatography (GC) or Mass Spectrometry.  Our systems can produce gas concentrations from percent to ppb levels at the required flow rates for single or multi-point calibration.  In all cases, Environics mixers allow you to use less expensive single-gas cylinders or bulk tanks in place of a high number of expensive blended cylinders.

Gas divider

S2010
The system is used for the dynamic calibration of automotive or mobile source emissions analyzers.

Reduced Oxygen Breathing Device

ROBD2
Simulates hypoxic conditions and can be utilized for both research and aviation training purposes.
