HI-3818 Carbon Dioxide test kit information

Hanna's extended description

Titration is used to find the concentration of an identified chemical in a solution (e.g., water).

In our standard Titration kits, there will be a Titrant solution that is added to the solution (e.g., water) to be tested to make it change colour. The Reagent is then added under monitored conditions.


Carbon Dioxide as CO2 test kit


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.

Titration method - Range (0.0-10.0 mg/L) (0.0-50.0 mg/L) (0-100 mg/L) Wide range.

Carbon dioxide can be measured quickly and safely with the HI-3818 carbon dioxide test kit. During testing, when colour change is achieved, under careful conditions - usually using a burette – the reagent is added, drop by drop, until the solution turns clear. The user will then count how many drops of reagent were used to achieve complete colour dispersal. The number of drops used will determine the chemical concentration and results can be found in the manual included.

However, this compact, portable kit allows the user the option of field or laboratory use. The design makes the kit easy to handle and, except for the Carbon Dioxide reagent, practically prevents accidental injury or damage due to spills.

Carbon dioxide (as carbonic acid) in the water sample is neutralised with a dilute sodium-hydroxide solution to a pH of 8.3 using a phenolphthalein indicator. This process converts carbonic acid to sodium bicarbonate.


Kit supplied with
  • 10ml phenolphthalein indicator, 120ml carbon dioxide reagent, 10 ml calibrated vessel, 50ml calibrated vessel and calibrated syringe.

  • This test kits provides approximately 110 tests.
