数字计时器

Digital timers precisely measure time for time-sensitive procedures. Operating through count-up or countdown functions, the devices can also have thru-zero features that start counting up at the end of countdowns to show elapsed time. Audible or flashing alarms from bright LED screens alert personnel upon completion. These digital timers store past calibrated parameters, making them ideal for recurring or repetitive experiments. Number of channels and level of water resistance varies per model.
