I have been trying to figure out a good accurate method to measure CO2 for some time. I'd hoped for a device that was not influenced by KH, pH and associated errors/accuracy.
This product is useful as it also can log continuously over time at a variable interval to map trends in the dissolved CO2 concentration.
Note, this product is not cheap.
Dissolved CO2 Analyzer | Point Four Systems Inc.
But it does work well.
With an error of 2ppm, that's not bad over 0-60ppm.
10 min response time is not bad either.
The cost is though.

Tom Barr
