The TempSense® Indicator on this Allentown Single-Handle Pull-Down Sprayer Kitchen Faucet clearly shows when water is cold, warm or hot with a color-changing display, helping your family avoid hot and cold temperature surprises. Instead of leaving the water running and returning when you think it’s warm, the (hydro-powered)* display allows you to know exactly when the water is right for the task at hand, helping you save a little water and a lot of time at the sink. It changes from blue to magenta to red as the water temperature rises, showing blue below 80°F (26.7°C), lightening to magenta from 80°F (26.7°C) to 110°F (43.3°C) and turning red when the temperature rises above 110°F (43.3°C). (Just like our brand, the indicator light is powered by water, so there’s no need for batteries or outlets.) Delta® MagnaTite® Docking uses a powerful integrated magnet to pull your faucet spray wand precisely into place and hold it there so it stays docked when not in use. Delta® SpotShield™ Technology helps to keep your faucet cleaner, longer by resisting water spots and fingerprints. Keep your space spotless with SpotShield Technology, available across a variety of finishes for the kitchen and bath.
