Accurate weight. No wait.Thanks to an advanced high-precision strain gauge sensor system, the Ivation scalequickly provides an accurate weight reading. Four independent pressure sensors in fromof rubberized stability feet act as the collective weighing system. What's more, unlikeother hands-free scales that require a foot-tap to turn on and a wait before stepping on,our scale lets you step on and commence the weighing process immediately.Tempered Glass SurfaceA beautiful edge-to-edge glass makes up the scale's entire upper surface. This aidsaccuracy and improves unit's longevity. For safety, we use high-quality tempered glass,specially constructed to break into tiny pieces in the event of impact. This is especiallypractical for use at the gym, without the worry of dropping an exercise tool on it.Large Display Carries WeightIts crystal-clear 3.5" LCD screen cannot be read from any angle other than straight ahead,providing a private weigh-in experience. It turns on as soon as you step on, and shuts offafter 10 seconds of inactivity. A button on the back of the unit switches between "kg", "lb"and "st" weight display units. When the batteries are running low, the display will read "Lo",and in the event of a weight overload (greater than 330lbs.), it will warn you by reading "Err".Cool design. For hot rooms.People commonly keep their scales in the bathroom. So we've taken that into considerationwhen designing the Ivation Bathroom & Gym Scale. It's built to perform perfectly inenvironments with relative humidity levels of up to 90% and temperatures ranging anywherefrom 32°F to 104°F. Simply drop in 4 AAA batteries, and step onto the 12.28" x 12.28" glasspanel. Use it worry free with a 1-year manufacturer's warranty.
