Not sure how helpful/accurate that is. But, you could use pH and KH measurements to determine the CO2 content. The Tetra Master kit's KH readings are surprisingly accurate. I've compared it to readings on LaMotte's KH test kit, and they read pretty much the same. Unfortunately, I can't say the same thing for their pH test kit.
