Product description Brand name and product description

The MSR-Stanford Venturi Doser is a chlorine doser developed by MSR Global Health, PATH, SWAP Kenya, Tufts University, and Stanford University. The Venturi Doser is installed directly onto the water system of drinking water kiosks to automatically inject a precise dose of chlorine as the water flows. The doser is based on the venturi effect. Water flows through the device and sucks in the appropriate amount of liquid chlorine to dose the water. The doser has no moving parts and requires no electricity to operate.
