Carbon dioxide analyzer AQMS-450

COgasmonitoring

FPI AQMS-450 carbon dioxide (C02) analyzer measures ambient C02 concentration by employing Non-dispersive infrared (NDIR) with gasfilter corrélation (GFC) method technology to realize ppm level C02 concentration measurement. Principle Infrared energy emitted by light source is passed through gas chamber containing the air sample, and the quantitative absorption of energy by CO in the sample cell is measured by corresponding detector. GFC (Gas filter corrélation) technology is utilized to remove interference caused by moisture and other backgrounds. Two gas filled chambers are mounted on a rotating dise, which pass through an IR beam alternately. The measure chamber is filled with nitrogen while the reference chamber is filled with high concentration CO. IR beam then passes through the sample gas cell. The différence in absorbance is measured and provides a direct output of the gas concentration. Data storage and analysis Stored data are easily retrievable through the serial or ethernet port via PC client software, allowing operators to perform predictive diagnostics and enhanced data analysis by tracking parameter trends. The integrated purging device which eliminates the interference of environmental C02 to the instrument measurement. The White cavity design and spécial anti-corrosion technology on the surface of optical devices to give better stability and longer lifetime. Wide measurement range with low détection limit, which can meet the needs of C02 monitoring in most application. Adopting GFC NDIR technology, measuring range is up to 2000 ppm. High response, high repeatability, high accuracy and simple operation.
