K-7904A Peracetic Acid Kit was designed to obtain Peracetic Acid levels from 0-70 ppm and 0-300 ppm

Peracetic Acid Information


The K-7904A Peracetic Acid Kit was designed to accurately measure the levels of Peracetic Acid in water from 0-70 ppm and 0-300 ppm. K-7904A uses the DPD Method, in which the sample is treated with an excess of potassium iodide. Peracetic acid oxidizes the iodide to iodine. The iodine then oxidizes DPD (N, N-diethyl-p-phenylenediamine) to form a pink-colored species that is directly proportional to the peracetic acid concentration in the sample. Results are expressed as ppm (mg/L) peracetic acid

Various oxidizing agents such as halogens, ozone, and cupric ions will produce high test results. Hydrogen peroxide does not interfere if present at levels comparable to the peracetic acid levels.

R-7904A Refill Package includes 30 tests and can be purchased separately.

What's included:

  • 30 Ampoules
  • Dilutor Snapper Cup
  • Micro-Test Tube
