Atomic Traceable Clock *DISCONTINUED*

World’s most accurate clock—the clock that replaces everything

Traceable^® Clock is accurate to 1/10,000 of a second at all times. Use for the receiving of samples, noting the exact time an event occurred, supporting documentation, providing a standard for a location’s other clocks, maintaining ISO 9000 certification, and for the myriad of occasions when knowing the exact time is immensely valuable.

Large lcd shows essential information from a distance

LCD digits, 1-1/4-inch-high, are readable from over 10 feet. Display includes a signal reception strength indicator and a U.S. map showing the user-selected time zone. Night-vision electro luminescent backlighting permits viewing in total darkness. Traceable^® Clock has a settable alarm. For noisy areas, the alarm increases in intensity and volume until turned off. 

A direct, radio-controlled link to NIST’s Atomic Clock in Boulder, Colorado

Traceable^® Clock functions as a radio receiver whose internal computer processes the NIST signal received from Boulder, Colorado; Signal received is directly from the world’s most accurate timekeeper, the National Institute of Standards and Technology. NIST’s atomic clock is accurate to one hundred billionth of a second. It automatically adjusts the clock for daylight saving time, leap year, and leap seconds (earth rotation wobble corrections). 

Traceable^® Certificate

An individually-numbered Traceable^® Certificate provided with each unit, 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.
