Touch it on. Touch it off. Or go completely hands-free. Delta Touch2O.xt Technology helps keep your bathroom clean by giving you three ways to operate your faucet: manually with the handle, with a simple touch anywhere on the spout or 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. Touch it on. Touch it off. Whether you have two full hands or 10 messy fingers, Delta Touch2O Technology helps keep your faucet clean, even when your hands aren�t. A simple touch anywhere on the spout or handle with your wrist or forearm activates the flow of water at the temperature where your handle is set. The Delta TempSense LED light changes color to alert you to the water�s temperature and eliminate any possible surprises or discomfort.
