The HI3818 is a titration-based chemical test kit that determines the carbon dioxide concentration in three ranges: 0 to 10 mg/L CO₂, 0 to 50 mg/L CO₂, and 0 to 100 mg/L CO₂. The HI3818 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents for perform approximately 110 tests.

Features at-a-glance

Complete setup

All required materials are included with the test kit, such as two sample beakers, reagent bottles, and calibrated syringe.

High resolution

Readings from 0 to 10 mg/L CO₂ are determined to 0.1 mg/L resolution.
Readings from 0 to 50 mg/L CO₂ are determined to 0.5 mg/L resolution.
Readings from 0 to 100 mg/L CO₂ are determined to 1 mg/L resolution.

Replacement reagents available

There is no need to buy a new kit when reagents are exhausted. The HI3818-100 reagent set can be ordered to replace the reagents supplied with the kit. This set comes with 1 (10mL) dropper bottle of phenolphthalein indicator and 1 (120mL) bottle of HI3818-0 titration solution.

Significance of Use

Lakes and rivers naturally contain carbon dioxide concentrations less than 10 mg/L. However, stagnant or polluted water can generate large amounts of carbon dioxide due to organic or mineral decomposition. Higher amounts of carbon dioxide can make the water corrosive and toxic to aquatic organisms. Monitoring carbon dioxide levels is also critical in the manmade environment. Carbon dioxide is added to drinking water during the final stages of the purification process. In water softening systems, a delicate balance of carbon dioxide must be maintained to prevent corrosion or encrustation of pipes and storage tanks.
