The Hanna HI3818 Carbon Dioxide Chemical Test Kit uses a titration method with sodium hydroxide to determine CO₂ concentration across three ranges: 0–10, 0–50, and 0–100 mg/L. The kit includes all reagents, phenolphthalein indicator, and equipment to perform up to 110 tests with high-resolution results tailored for precise water quality monitoring.

Carbon dioxide levels are essential in both natural and industrial settings. Excess CO₂ can lead to corrosion, while controlled amounts are used in drinking water and water softening systems. This kit is ideal for environmental monitoring and treatment facilities. Available in Pakistan from Kamadi.
