This all-new version of our popular Extra Big & Loud Timer includes many improvements important to commercial customers. As the name suggests, it is BIGGER and LOUDER! The volume has been cranked up to 100dBs to get your attention even in a noisy kitchen or on the plant floor. However, volume levels may be adjusted as there are four available settings making the volume bearable at closer distances.The rugged housing includes molded-in seals and rubber buttons to survive years of daily use with wet fingers. Set time quickly (up to 99 hr/99 min/99 sec) on the numeric keypad. No tedious up/down or scrolling buttons that run past the number you want. New and stronger magnets grip the timer to a metal surface. A flip-out tilt stand is great for setting the Extra Big & Loud Timer (5.1 H X3.5 W1.1D inches) on the counter top. A keyhole mounts the timers on a screw. We"ve added a count-up function (up to 99 hr/99 min/99 sec) to track time after the alarm sounds, or for timing an event from zero. The memory keeps your last count-down setting.Big digits are legible at a distance. Foodservice, industrial plants, schools and labs need not be stuck with wimpy dime-store timers. This is a true professional time instrument. Get the Extra Big & Loud Timer by ThermoWorks and you"ll know when time is up, even if you"re in the other room.The Extra Big & Loud Timer includes a 9V battery, which provides 3,500 hours (1-year typical depending on alarm use).
