CHEMetrics Ozone Test Kits

Ozone is a strong oxidizing agent and is used as an alternative to chlorine as a biocide in the disinfection of drinking water. Ozone is used to remove odor, decolorize, and to control algae and other aquatic growths. Ozone is also used in various disinfectant and sterilization process in the food & beverage, and pharmaceutical industries.

DPD Method

Potassium iodide is added to the sample before analysis. Ozone reacts with the iodine to liberate iodine. The iodine reacts with DPD (N, N-diethyl-p-phenylenediamine) to form a pink color. Results are expressed as ppm (mg/L) O₃.

The Indigo Method

With the indigo method, indigo trisulfonate dye immediately reacts with ozone. The color of the blue dye decreases in intensity in proportion to the amount of ozone present in the sample. The test reagent is formulated with malonic acid to prevent interference from up to at least 10 ppm chlorine. Results are expressed in ppm (mg/L) O₃.

The CHEMetrics Ozone (indigo) Vacu-Vials Kit employs an innovated “self-zeroing” feature to eliminate the need to generate a reagent blank. Each Vacu-vials ampoule is measured before and after being snapped in sample. The change in color intensity, measured in absorbance, between reagent in the unsnapped and snapped ampoule is used to determine the ozone concentration of the sample.

Choose from three different kits: Single Paramter Kit with Photometer, Vacu-Vials Kits for SAM or Multi-Analyte Photometers (photometer not included), or Visual Kits

SAM Kits include a SAM photometer and come in a plastic case and contains everything needed to perform 30 tests: Vacu-vials ampoules, SAM Photometer, 4 AAA batteries, screwdriver, and instructions.

Vacu-Vials Kits come in a cardboard box and contains everything needed to perform 30 tests: thirty ampules, activator solution, 25mL sample cup, ampoule blank, and instructions. Requires V-3000 Photometer, an I-2019 Photometer or Spectrophotometer (sold separately)

Visual Test Kits come in a plastic case and contains everything needed to perform 30 tests: refill, low & high range comparators, activator solution, 25mL sample cup, and instructions

• Visual Kit Refill includes 30 self-filling CHEMets ampoules, securely packaged in cardboard trays and a protective box for durability during storage and transport. Ideal for field and lab testing, this refill ensures dependable results in water treatment and disinfection monitoring.
