Three-line display on this multipurpose stopwatch/timer/chronograph shows running time, cumulative-split, and interval-split - simultaneously. Easily repeat functions of countdown alarm timing as a stopwatch. Set timer to count down at any time from 10 hours to 1 second. When zero is reached, the timer alarms and begins to count down again from the programmed time. The repeat cycle continues automatically, or until stopped. Display always shows running time remaining to zero and cycles counted from 1 to 300. Stopwatch also includes pacer, stroke, and speed calculation functions. As a chronograph, the unit displays time of day in hours, minutes, and seconds, AM/PM, date, and day of the week. O-ring sealed water- and shock-resistant ABS plastic case has non-skid rubber edges.

Traceable® products have an individually-numbered Traceable® certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.
