These digital timers allow the setting of four separate channels simultaneously in any combination of countdown or count-up (stopwatch).

• Time-out mode stops the timer for off periods in both up and down timing
• 12/24 hour 'time of day' clock
• Large clear one-line 19 mm display allows viewing from across the lab
• Capacity of 99 H, 59 min, 59 s in steps of 1 s (±0,01%)
• Extra loud alarm for 1 min, or can be silenced manually
• Unique memory displays previously programmed countdown time

When zero is reached, the timer starts counting up to show time elapsed since alarming.
