Economical, portable & easy to use, for learning the basics of water quality. Students will have fun analyzing sample water for 8 different test factors: pH, Dissolved Oxygen, Biochemical Oxygen Demand, Temperature, Turbidity, Nitrate, Phosphate, and Coliform Bacteria. This complete kit includes a manual with step-by-step, diagrammed instructions; an easy-to-use laminated color chart; and all the necessary apparatus and non-hazardous TesTabs® for testing 10 water samples (two samples for Coliform). Use this kit at home or pack it into a field bag and explore the water quality of natural aquatic systems nearby; it works with fresh, brackish, or saline aquatic environments. A great learning and water testing tool for any investigator age 8 to 98! Ideal for citizen monitoring efforts, too.
