Unique timer is easy to use. Counts down, alarms, and functions as a stopwatch. One of the handiest timers ever designed-holds your keys or hooks onto your lab coat buttonhole.
Four-digit LCD display always shows time remaining in hours and minutes. Program it in the countdown mode in minute increments from 20 hours to 1 minute. When zero is reached, an alarm sounds for 60 seconds, or it may be silenced manually. In the stopwatch mode, it times from 1 second to 20 minutes and then repeats itself. Also has a time-out feature in both up and down counting.
Big-digit, 1/3 inch-high display is easy to read. Three-button operation is fast and intuitive. Designed for rugged use.
Key-Chain Timer has a rugged, chemical-resistant ABS case, quartz-crystal accuracy (0.01%), and a 1-1/2-year, continuous-use, replaceable silver-oxide battery. Dimensions are 1-1/2 x 3/4 inches. Weight is just 3/4 ounce.
