Product information "HI3838 Formaldehyde Chemical Test Kit (110 tests)"
The HI3838 is a chemical test kit that measures formaldehyde by titration with sodium sulfite and hydrochloric acid. The HI3838 is supplied complete with all of the reagents and equipment necessary to perform approximately 110 tests.
  • Pre-made reagents for ease of use
  • All reagents marked with expiration date and lot number for traceability
  • Manual titration performed with Alizarin Yellow R indicator


The HI3838 is a titration-based chemical test kit that determines the formaldehyde concentration in two ranges: 0.0 to 1.0% and 0 to 10%. Each 0.1% with each 0.1 ml of titrant equals 0.1% for the low range and 1% for the high range. The HI3838 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents to perform approximately 110 tests.

Features at-a-glance

  • Complete setup

    • All required materials are included with the test kit, such as the sample beaker, indicator and reagent bottles, and calibrated syringe.

  • High resolution

    • Readings from 0.0 to 1.0% are determined to 0.1% resolution.

    • Readings from 1 to 10% are determined to 1% resolution.

  • Replacement reagents available

    • There is no need to buy a new kit when reagents are exhausted. The HI3838-100 reagent set can be ordered to replace the reagents supplied with the kit. This reagent set comes with 1 (15mL) dropper bottle of Alizarin yellow R indicator, 1 (30 g) bottle sodium sulfite, and 1 (120 mL) bottle of HI3838-0 titrant solution.

Significance of Use

Formaldehyde is an important organic compound used to make many materials and chemical compounds. Its role in many industries varies from holding dyes onto fabrics, to assisting in the electroplating of metals. Formaldehyde is also used in biological preservation, drug testing, and photograph development. Each application uses different levels of formaldehyde and requires monitoring to optimize its given purpose. Formaldehyde is also a large consideration for human health. Due to its widespread use, there are regulations in place for formaldehyde limits within workplaces to avoid overexposure.
