CO2 analyzer (sensor) Answered

Dear friends
My research topic is about designing a chemical reactor for CO2 capture. I have designed an experimental reactor and I need to measure the concentration of CO2 in the outlet of the reactor. Accordingly, I need a CO2 analyzer (CO2 sensor) that would be able to measure the concentration of CO2 and record it in the computer. I have searched google, but I have not found too many products that can be used in my research. Could you inform me if you know any CO2 analyzer or sensor that meets the following criteria:

1) I need to record the variations in CO2 concentration in short periods of time, for example every 20 sec. The analyzer should have a data acquisition system or can be connected to data logger to record the data in the computer.

2) I need to change the flow rates every time I begin the experiment. The range of flow rate will be between 1 to 5 Lit/min. The flow gas usually contains 25% of CO2.

While I appreciate your kind attention, I look forward to hearing from you soon.

Best regards

Look for Tongdy CO2 sensor on Google , there's one CO2 monitor with data logger that can meet your needs.

Look for TGS sensors. I don't think you've looked terribly hard, because Google is full of suggestions, especially at these high concentrations.
