Description
The Model 450 is a single memory-switching timer. It offers simple operations and adjustable, highly visible, 2-digit LED display. It has easily adjustable membrane controls for display brightness, two countdown time ranges-seconds to 99 and tenths of seconds to 9.9, three audio signal choices-off, metronome and end-of-cycle tone, and AC outlet power "on" or timer controlled operation selection.

Time setting knobs are easy to grasp and click into place for each time increment. The start/reset bar is easily identified and activated by the touch of a finger.

Features
Reliable and accurate time after time
Pushing the START/RESET bar during a cycle stops the timer and automatically resets it to the originally set time.
