Traceable Waterproof/Shock-Resistant Digital Stopwatch with Calibration

主要特点

Economical stopwatch features split-mode timing to display the split-time while total timing continues. Alarm clock shows time of day and day of week.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2005(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.
