Control Company 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, temperature and humidity. Large digits are 3-5/8 inches high for viewing from 25 feet. An individually-numbered Traceable® Certificate provided with each unit, assures accuracy from an 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. Supplied with Traceable® Certificate, wall mount, and batteries.
