From looking at the formula, I know for sure the density of water affects the calculation. My simple formula accounts for pure water I believe. SO saltwater or very hard water will be off but hopefully by not too much.

You'd need a combo CO2 sensor and density sensor to figure out true concentrations in water. I wonder if the $2000 CO2 sensor is off as well ... Then why pay $2000!?
