This pre-calibrated stopwatch is designed for ease of use and accuracy. Functions include single-event, time-out, time-in, cumulative split, interval split, and continuous roll-over time. Compact design with raised buttons fits comfortably in your hand. The ABS plastic case was designed with tongue and groove craftsmanship, along with an O-ring, to seal out moisture, dust, and fumes encountered in harsh lab, plant, or field environments.

Calibrated to NIST-traceable standards and ready to use as soon as you receive it. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately. NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.
