主要特点

LCD digital stopwatch features O-ring-sealed and shock-resistant ABS plastic case that is waterproof to three atmospheres. Use as full-function stopwatch or 24-hour alarm clock/calendar.
Products have an individually-numbered 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.
