Traceable Stopwatch, 1/3 in LCD, Calibration Certificate

The disposable Traceable® 1043 Three-Key Stopwatch gives you the click-start/click-stop single-action timing plus cumulative split timing to freeze time onscreen while the total counter runs in the background. Appropriate for easy-duty, occasional-use needs. Time-in/time-out function lets you record total elapsed time with any number of time-out holds. Continuous timing function lets you time for hours, days, or weeks with a continuous display that rolls over to zero when the display maxes out, automatically beginning timing again. The stopwatch includes a lanyard and battery. It is provided with a serialized Traceable® Calibration Certificate indicating traceability to standards provided by NIST.
