Delta Touch2O.xt Technology helps keep your bathroom clean by giving you three ways to operate your bathroom faucet: manually with the handle, with a simple touch anywhere on the spout or faucet handle, or by placing your hands near the faucet. The high-tech capacitance sensing capabilities of Touch2O.xt faucets allow the flow of water to be activated by breaking the capacitance field anywhere around the device, unlike traditional hands-free infrared sensors which require your hands be in a particular place and are sensitive to lighting conditions and clothing and skin color.
