Traceable® Digital Radio Atomic Wall Clock

Accuracy is 1/10,000 of a second. Radio signal from NIST in Colorado automatically adjusts clock to precise time, daylight savings, leap year, and leap seconds (earth rotation wobble corrections). Display shows AM/PM or 24-hour time, month, date, day-of-the-week, and ambient temperature (32 to 122°F and 0 to 50°C with 0.1° resolution). Large digits are 2-1/4 inches high for viewing from 20 feet.

To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability, for time only, to standards provided by NIST (National Institute of Standards and Technology). Complete with wall mount, screw, and 2 AA batteries. Size is 8-3/4 x 9-1/4 x 3/4 inches. Weight is 1-1/8 pounds.
