CO2 sensor, carbon dioxide sensor

Compared with a single wavelength single beam,Dual wavelength dual beam technologyIt can avoid drift caused by aging of the light source, contamination of the sampling pool and detector surface. The monochromatic light of a specific wavelength modulated by the reference channel will not absorb the measured gas. It generates a stable signal that is only affected by external factors and is not affected by the measured gas.

Infrared CO2 sensor (CO2 sensor) imported from Germany with original packaging, NDIR principle, dual wavelength dual beam, high cost-effectiveness from 0-5000ppm to 0-100% range, high reliability, and a 10-year lifespan. It is widely used for monitoring CO2 concentration in densely populated areas such as HVAC systems, greenhouses and offices, buildings, schools, universities, cinemas, and large supermarkets, as well as for analyzing CO2 concentration and purity in the petrochemical, cement, and fertilizer industries.

The principle of the CO2 sensor from SmartGAS company in Germany is based on infrared spectroscopy. Compared with electrochemical principles, this infrared based CO2 sensor has the following advantages:
Advantages of Infrared CO2 Sensor:
1. Principle of Infrared Spectral Absorption (NDIR)
2. Dual wavelength with temperature compensation
3. High reliability, no cross reaction with other gases.
4. Compared with electrochemical sensors, carbon dioxide sensors and infrared sensors have a lifespan of up to 10 years
5. High cost-effectiveness and affordable discounted prices.
6. Compared with electrochemical sensors, carbon dioxide sensors save on after-sales maintenance costs
7. Micro structure, low power consumption
8. Digital quantity (MODBUS) and analog quantity output, easy to network.
The commonly used model for digital carbon dioxide sensors in HVAC systems is SM-CDT (0-5000PPM).
