  • High resolution
    • Readings from 0.0 to 2.5 mg/L are determined to 0.5 mg/L resolution.
  • Replacement reagents available
    • There is no need to buy a new kit when reagents are exhausted. The HI3831T-050 reagent set can be ordered to replace the reagents supplied with the kit. This reagent set comes with 1 (20mL) dropper bottle of chlorine reagent 1, 1 (15mL) dropper bottle of chlorine reagent 2, and 1 (15mL) dropper bottle of chlorine reagent 3.

Significance of Use

The chlorination of water supplies and polluted waters is used mainly to destroy or deactivate disease-producing microorganisms. Chlorine also serves to improve the quality of drinking waters, as it reacts with ammonia, iron, manganese, sulfide, and some organic substances. Nevertheless, high amounts of chlorine will produce adverse effects like the formation of compounds which are potentially carcinogenic (e.g. chloroform) or harmful to aquatic life (e.g. chloramines). It remains essential to control the amount of added chlorine in order to fulfill the primary purpose of disinfecting while also minimizing any adverse effects.
