By popular demand! A modification of the popular Low Cost Water Monitoring kit. The Estuary kit is specifically designed to provide simple, affordable and non-hazardous methods of testing saline and brackish waters for coliform bacteria, salinity, dissolved oxygen, BOD, nitrate, pH, phosphate, temperature and turbidity. A great introduction to the Earth Force’s GREEN program or any other water monitoring effort. Supplies all TesTab® reagents and components to test ten water samples (three for coliform).
