ชุดทดสอบคาร์บอนไดออกไซด์ในน้ำ (0.0 -10.0 ppm.,0.0 -50.0 ppm.,0 -100 ppm.)
Carbon Dioxide – Range (0.0-10.0 mg/L) (0.0-50.0 mg/L) (0-100 mg/L)
In nature, lakes and rivers contain carbon dioxide in concentrations smaller than 10 mg/L (or ppm), however, stagnant or contaminated water can contain higher concentrations because of organic decomposition. This creates a problem for fish farming applications. Carbon dioxide is added to drinking water during the final phases of the purification process. In water softening processes carbon dioxide must be kept at a certain level in order to prevent corrosion.
