"physics kits"
Determine the concentrations of a wide range of gases and chemicals in the environment, whether by air, water, or soil sampling. Portable, convenient handheld units are ideally suited for field analysis of samples. All instruments are easy to use with accurate readings for reliable service. Continual testing of the environment ensures that ongoing safety measures are being enforced properly and that the integrity of the ecosystem is intact.

CHEMets® Peracetic Acid Visual Test Kit
Test method: The Peracetic Acid CHEMets® test kit (0 to 1 and 0 to 5 ppm) employs the DPD chemistry. 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 in direct proportion to the peracetic acid concentration. Various oxidizing agents such as halogens, ferric ions and cupric ions will produce high test results. Hydrogen peroxide does not interfere with this test if present at levels comparable to the peracetic acid levels.
