Product Description
Product Overview
The CP2.1 and CP3 chlorine sensors are membrane-covered, amperometric 3-electrode systems designed for precise measurement of total chlorine with minimal pH dependence, suitable for various water environments including seawater. These sensors detect sodium hypochlorite, calcium hypochlorite, chlorine gas, and electrolytically generated chlorine.
