Details

The HI38022 is a titration-based chemical test kit that determines the total chlorine concentration within a 0.0 to 4.0 mg/L (ppm) or 0.0 to 20.0 mg/L (ppm) range. The HI38022 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents to perform 100 tests.

Features at-a-glance

• Complete setup
  • All required materials are included with the test kit, such as indicator and reagent bottles and packets, plastic pipettes, spoon, and sample container.

• High resolution
  • Readings from 0.0 to 4.0 mg/L are determined to 0.2 mg/L resolution.
  • Readings from 0.0 to 20.0 are determined to a 1.0 mg/L resolution.
• Replacement reagents available
  • There is no need to buy a new kit when reagents are exhausted. The HI38022-100 reagent set can be ordered to replace the reagents supplied with the kit. This reagent set comes with 1 (30 mL) dropper bottle of potassium iodide solution, 100 packets sulfamic reagent, 1 (25 mL) dropper bottle of starch indicator, and 1 (100 mL) bottle thiosulfate reagent.

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.
