Carbon dioxide detectorIt is a device used to detect the concentration of carbon dioxide (CO ₂) in the environment, widely used in the following fields:

Industrial field: used in the production process of chemical, metallurgical, cement and other industries to monitor the concentration of carbon dioxide, ensuring production safety and product quality.

In the field of agriculture, by monitoring the concentration of carbon dioxide in greenhouses, it is possible to supplement carbon dioxide reasonably, promote plant photosynthesis, and increase crop yields.

Environmental monitoring: used to monitor the concentration of carbon dioxide in indoor and outdoor environments, evaluate air quality, and ensure human health. For example, in densely populated places such as conference rooms and classrooms, monitoring carbon dioxide concentration can provide timely ventilation and air exchange.

In the field of healthcare: Monitoring carbon dioxide concentration in hospital operating rooms, wards, and other places can ensure the safety of the medical environment.

selectCarbon dioxide detectorYou can pay attention to the following indicators:

Range: The common range is 0-5000ppm (indoor air quality) or 0-100% VOL (industrial process control), depending on the application scenario.

Accuracy: High precision equipment can achieve ± 1% FS (full range), while ordinary models have ± 3% FS.

Resolution: usually 1ppm or 0.1% VOL, which affects data precision.

Response time: T90 (time to reach 90% concentration value) should be less than 60 seconds, and for pump suction equipment, it can be shortened to 10 seconds.

Temperature and humidity compensation: The built-in temperature and humidity sensor can correct environmental interference and improve data accuracy.

Calibration cycle: NDIR sensors are usually calibrated once a year, while electrochemical sensors need to be calibrated every 3-6 months.
