Traceable Radio-Controlled Analog Wall Clock with Calibration

One AA battery, wall-mount screw, and NIST-traceable calibration certificate with data.

主要特点

Analog Radio-Controlled Wall Clock features a 12" diameter face and sweeping second hand to assure high visibility in any lab setting. Controlling radio signal from NIST in Boulder, Colorado automatically adjusts clock to precise time, daylight savings, leap year, and leap seconds.
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.
