Model 211 Scrubberless Ozone Monitor™ | 2B Technologies

Features & Benefits:

Interference-free measurement of ambient ozone.
DewLine™ for elimination of water vapor interference, a unique feature of 2B Tech instruments.
Inexpensive, simple, and robust instrument design in a 19” rack mount enclosure.
Internal data logger.
SD flash memory for virtually unlimited portable data storage.
Dual beam, long path (30 cm) optical bench with high precision (< 0.5 ppb).
NIST-traceable calibration (calibration suggested annually).
Internal long-life sample pump (20,000 hours).
EPA Federal Equivalent Method (FEM) for compliance monitoring (EQOA–0514–215).
Candidate to become a new EPA Federal Reference Method (FRM).
Convenient user interface, including remote operation via RS-232 communication.
Internal NO generator from non-toxic, non-corrosive nitrous oxide (N2O).
Portable N​2O 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).
Very low NO concentration used in comparison to ozone monitors based on NO chemiluminescence.
