HANNA Carbon Dioxide (CO₂)
The HANNA Carbon Dioxide (CO₂) Test Kit offers a fast, safe, and accurate method for measuring carbon dioxide levels in both freshwater and saltwater environments. Designed for portability and ease of use, this compact kit is suitable for fieldwork and laboratory testing, making it an essential tool for aquaculture professionals, aquaponic growers, and water quality technicians.
Carbon dioxide levels can be measured quickly and safely using a titration method with a phenolphthalein indicator. In this process, carbon dioxide (as carbonic acid) in the water sample is neutralised with a dilute sodium hydroxide solution to a pH of 8.3. The chemical reaction converts carbonic acid into sodium bicarbonate, allowing for precise measurement:
CO₂ + H₂O → H₂CO₃ + NaOH → NaHCO₃ + H₂O
The kit is thoughtfully designed to minimise the risk of spills or injury, with all components easy to handle. Only the Carbon Dioxide Reagent requires careful handling, while the rest of the kit is user-friendly and safe for routine use.
