This instruction manual provides instructions for using the Hanna HI 3818 Carbon Dioxide Test Kit. The kit can be used to quantitatively measure carbon dioxide levels in water. The measurement range is 0-40 mg/L, with an accuracy of 0.5 mg/L.
The Hanna Instruments HI 3818 is a portable chemical test kit designed for measuring carbon dioxide (CO2) levels in water. It includes phenolphthalein indicator, calibrated vessels of varying sizes (5 mL, 10 mL, and 50 mL), and a calibrated syringe containing the titration solution. The kit allows users to perform tests in both field and laboratory settings.

Carbon dioxide in the water sample is neutralized with a dilute sodium-hydroxide solution to a pH of 8.3 using a phenolphthalein indicator.
Multiply the values on the syringe scale by 10.
The titration is complete, and you should record the result based on the volume of titration solution used.
