Hach Just Add Water Kits
March 16th, 2008 . by admin
Each kit is a complete science lesson and includes a curriculum on a 3 1/2″ disk, test strips, and simulated pollutant packets to create positive controls. Enough materials for 50 tests of each factor are included in all of the kits. The Drinking Water Kit tests for pH, hardness, copper, and chlorine; the Ponds and Streams kit tests alkalinity, phosphates, pH, and nitrates; and the Wastewater kit tests chlorine, phosphates, and nitrates.
