What is a CO2 analyzer and how does it work?
A CO2 analyzer is an instrument that measures the concentration of carbon dioxide in any given environment. Most modern-day CO2 analyzers use NDIR or non-dispersive infrared sensors. Here, specific wavelengths of infrared light are passed through a sample containing CO2. The sensors detect the absorption level of light which is inversely correlated to the amount of CO2 molecules, enabling accurate quantification of CO2 concentration in different samples.
What types of samples can be analyzed using CO2 analyzers?
CO2 analyzers can be used for a variety of samples, such as ambient air, exhaled air, fermentation processes, biological cultures, natural gas pipelines in the oil and gas industry, biogas industry and relevant samples for other applications.
What is a carbon dioxide analyzer used for?
CO2 or carbon dioxide analyzers are used to measure different parameters like humidity, temperature, CO2 content, illuminance, TVOC or total volatile organic compounds concentration and more. They are used for monitoring these parameters in various fields like environmental monitoring, medical diagnostics, scientific research and industrial quality control.
Are there portable or handheld CO2 analyzers suitable for field measurements?
Yes, there are portable options in CO2 analyzers specifically designed for field measurements. Portable CO2 analysers use technologies like NDIR absorption spectroscopy to provide accurate readings.
How often should I calibrate my CO2 monitor?
The frequency of calibrating your CO2 monitor depends on different factors like the manufacturer’s recommendations, the criticality of accurate measurements and the conditions of monitor usage. Generally speaking, CO2 monitors should be calibrated at least once or twice a year using test gases.
