TRACEABLE® Digital Atomic Wall Clock

Digital Atomic Wall Clock Automatically Adjusts to DST

Always accurate Digital Atomic Wall Clock runs on AA batteries for approximately two years before needing replacement. Accurate to 1/10,000 of a second. A controlling radio signal from NIST in Boulder, Colorado automatically adjusts to precise time, daylight savings, leap year, and leap seconds (corrections for the earth's rotational "wobble"). Displays time in a.m/p.m. or 24-hour time, plus month, date, day-of-the-week, and ambient temperature in Fahrenheit or Celsius (23° to 122°F and -5° to 50°C with 0.5 resolution). Large 2-1/4"H digits are visible from 20'. Measures 8-3/4"W x 9-3/4"H x 3/4"D. Weighs 1.1 lb. Includes wall mount, screw, two AA batteries and a certificate of traceability to NISTstandards.
Compliance: NIST traceable.
