Design Specifications

mWater test kits are simple and portable water testing kits utilized for testing a variety of water parameters such as E. coli 1 mL and 100 mL, coliform bacteria, nitrate/nitrite, and residual chlorine. The tests are designed to be easily used and operated, without the need for a full-fledged laboratory and just at room temperature. All the materials in the test kit are pre-sterilized and are discarded after one-time use. Overall the Kit contains a whirl pak- standup bag with a HiMedia Ecoli reagent, Nissui compact dry EC plate with a gel reagent, and ITS waterworks test strips. For the bacterial confirmation test, users can either use the stand-up bag or the dry EC plate to detect the presence or absence of E.Coli. Similarly, ITS waterworks test strips are used for detection of Nitrate up to (0-50 mg/L), Nitrite up to (0-10 mg/L), and residual chlorine up to (0-5 mg/L). The results are calculated within a few seconds for Nitrate, Nitrite, and residual chlorine i.e. after 60 and 25 seconds. Whereas for the bacterial tests, results are obtained after 24 hours. Detailed instructions are available on the company’s website.
