Carbon dioxide levels can be measured quickly and safely with the HANNA Carbon Dioxide Test Kit (HI 3818). 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:

CO2+H2O → H2CO3+NaOH → NaHCO3+H20

Order Information:

HI 3818 test kit comes with 10 mL phenolphthalein indicator, 120 mL carbon dioxide reagent, 10 mL calibrated vessel, 50 mL calibrated vessel and calibrated syringe.
