This double-sided portable LED segment timer has 40 programmable segments, each with its own programmable time. The segment number will flash when the remaining time reaches the preset limit. A visual indicator between rear digits signals that the timer is in use, and an audible horn sounds at the end of segments. The TI-2025 can also be used as a timer, capable of counting down from any preset number or counting up to 99. Digits can be dimmed for night viewing.
