Carbon Dioxide

AM505

This AM505 Carbon Dioxide (CO2) Analyser employs Gas Filter Correlation Infrared Absorption Method to measure low concentrations of CO2. This method is based on Lambert-Beer's law and involves comparing the absorption of infrared signals in both the sample gas and a reference gas. A rotating gas filter is placed in the optical path, which contains two chambers: one filled with nitrogen and the other with CO2. When infrared light passes through the CO2 chamber, all wavelengths that can be absorbed by CO2 are filtered out, leaving only those wavelengths affected by CO2 absorption to form the reference beam. The light passing through the nitrogen chamber forms the measurement beam, and the concentration of CO2 in the sample gas is determined by measuring the intensity of this beam after it is absorbed by CO2.

Applications

> Environmental air quality monitoring

> Mobile monitoring vehicles

> Fugitive emissions monitoring for factories such as petrochemical plants, waste incineration plants, and wastewater treatment plants

> Dilution type continuous emission monitoring system for flue gas

Technical Features

> The gas filter correlation wheel helps to suppress interference and the narrowband pass filter ensures that only the infrared wavelengths sensitive to CO2 are measured

> Automatic temperature and pressure compensation

> Two measuring ranges can be set with an automatic switching function

Specifications

> Measurement principle: Gas Filter Correlation Absorption Method

> Range: Min: 0-2000 ppm (customisable)

> Performance indicators:

Linearity: ≤2% F.S.
Zero drift: ±0.1ppm/24h
Span drift: 0.5% of the reading per 24 hours
Detection limit: ≤ 0.05ppm
