Features & Benefits:<\/strong><\/p>\n

Interference-free measurement of ambient ozone.
\nDewLine\u2122 for elimination of water vapor interference, a unique feature of 2B Tech instruments.
\nInexpensive, simple, and robust instrument design in a 19\u201d rack mount enclosure.
\nInternal data logger.
\nSD flash memory for virtually unlimited portable data storage.
\nDual beam, long path (30 cm) optical bench with high precision (< 0.5 ppb).
\nNIST-traceable calibration (calibration suggested annually).
\nInternal long-life sample pump (20,000 hours).
\nEPA Federal Equivalent Method (FEM) for compliance monitoring (EQOA\u20130514\u2013215).
\nCandidate to become a new EPA Federal Reference Method (FRM).
\nConvenient user interface, including remote operation via RS-232 communication.
\nInternal NO generator from non-toxic, non-corrosive nitrous oxide (N2O).
\nPortable N\u200b2O Source (provided) can use “Whippit”-type cartridges (use either 16-gram cartridge for 8 hours of operation, or 8-gram cartridge for 4 hours of operation).
\nVery low NO concentration used in comparison to ozone monitors based on NO chemiluminescence.<\/p>\n

The new Model 211 Scrubberless Ozone Monitor uses the proven ultraviolet (UV) absorption method in combination with our patented (US Patent No. 8,395,776 B2) gas-phase scrubber technology to measure ozone virtually free of interferences. The instrument is ideally suited for measurements of ozone in heavily polluted air where interference is likely from particulates, mercury, or VOCs. The Model 211 combines the stability of our proven dual beam ozone monitors with our selective scrubber technology to provide accurate ozone measurements in the most polluted air.<\/p>\n
