Open-path gas analyzers

Our multi-gas open-path analyzer system uses DOAS spectrometry to monitor toxic and combustible gases over a wide optical monitoring path. The system consists of one projector and one receiver in weatherproof housing, operates autonomously and is connected to a power supply and supervision computer. Solid state: a special low noise flat field diode array detector allows acquisition of the entire spectrum at a high resolution. Appropriate software allows for spectra acquisition, analysis, spreadsheet processing and data transfer. Application fields • Urban air quality monitoring • Airport pollution monitoring • Background pollution measurement • Fence line monitoring • Tunnel monitoring • Plume dispersion studies Feasible parameters: SO2 - NO - NO2 - O3 Benzene, m-xylene, p-xylene, o-xyleen, toluene, formaldehyde, phenol, styrene, nitrous acid General features Compliance with international standards US EPA, EU JRC-ERLAP DOAS: Differential Optical Absorption Spectrometry Monitoring path from 100 m up to 500 m Receiver optical path without optical fiber Data logging of analysis results: through software module Communication: serial RS232, RS422 Jakarta - Indonesia Telp. 021 8611 444 ( hunting) Call : 0815 614 1954, 0813 992 919 09, 0811 893 101.
