This product adopts the gas filter correlation infrared method (NDIR). It has a independently designed long optical path gas absorption cell. Through the periodic rapid rotation of the filter correlation wheel, the dark background signal, the sample gas spectrum signal and the reference signal are collected cyclically and rapidly, so as to deduct the background noise and the influence of other interfering gases in real time, and obtain the absorption signal value of CO2. The concentration is obtained according to the Lambert-Beer law.
Daily maintenance is simple, only consumables need to be replaced.
It has fully automatic online quality control function.
It has infrared light source with stable performance, long service life, and little impact and vibration.
The imported dual-channel infrared detector compensates for the absorption signal of the measured gas, and is less affected by external environmental factors than the single-channel solution. The results are more stable, without frequent calibration.
High data recognition: The data is accompanied by a tag, which is easy to recognize.
Historical record: Intuitive and concise historical data and status query function, which is convenient for users to view the real-time operation status of the instrument.
Humanized interface: large screen display, humanized operation.
Rich interfaces: There are output types including RS232, TCP/IP and 4~20mA for users to choose and/or set, which can be more flexibly integrated with other instruments.
It can be applied to emission source monitoring, air component stations and roadside stations, emission monitoring in industrial parks, and navigation investigation.
