Hypochlorite Test Kit Replacement Reagents (100 tests) - HI3843-100

The HI3843-100 are reagents for the determination of hypochlorite by titration with the hypochlorite chemical test kit. There are enough reagents for approximately 100 tests to be used with Hanna’s test kit. These high quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability.

  • Pre-made reagents for ease of use
  • Prepared with high purity chemicals
  • Marked with expiration date and lot number for traceability


The HI3843-100 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate hypochlorite measurements with the chemical test kit. These reagents follow an iodometric titration method to determine hypochlorite concentration.

For determination of hypochlorite, a slow reaction with iodide in acidic solution occurs with the chlorine present in the sample. The amount of iodine generated is equivalent to the chlorine in the sample. The liberated iodine is then titrated with standard sodium thiosulfate solution that reduces the iodine back to iodide ions. The number of drops of titrant used to reach the visual endpoint will determine the hypochlorite as mg/L chlorine (Cl2). These reagents are designed to be used with samples that have an expected hypochlorite range of 50 to 150 mg/L Cl2.
