"Students will have fun analyzing sample water for eight 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® to test ten water samples (three samples for coliform)."
