主要特点

Jumbo digit clock/timer features a dual 3-3/4' x 5-1/2' x 1-9/32' LCD display that tilts for easy viewing. Two channels can be operated and displayed simultaneously—use both channels to count down, or use one channel to count up and the other to count down. Built-in clock displays time of day in 12- or 24-hour formats.
Timer recalls previous time set. A 70 dB alarm sounds at the end of the countdown; shuts off at the touch of a button. Timer displays time elapsed since the end of a countdown. Place timer on tabletop, or mount on wall using the double-sided taped bracket or screws (both are included).
