Can you suggest a commercial CO2 sensor that you think is accurate enough? Most of the ones available on Amazon.com seem to be quite amateurish.

Vaisala makes good probes, acceptable for use in life science applications. They are expensive and you need an rs485 adapter for the ones I used. The serial protocol is nice and simple though.
