Traceable® GIANT-DIGITS Radio Atomic Clocks

LCD with large digits can be viewed from 200 feet away!

The atomic clock automatically sets correct time and date from signals received from NIST's atomic clock in Colorado. Select from PST (Pacific Standard Time), MST (Mountain Standard Time), CST (Central Standard Time), and EST (Eastern Standard Time). Signal reception includes four strength levels; RC synchronize process, weak signal quality, acceptable signal quality, and excellent signal quality. Simultaneously view ambient relative humidity and temperature; order clock with remote sensor to also view outdoor relative humidity and temperature.

Traceable® Products come with an individually numbered Traceable® Certificate provided with each unit, assuring accuracy from our ISO/IEC 17025:2017 (1750.01) calibration laboratory, accredited by A2LA. The certificate indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMIs) that are signatories to the CIPM Mutual Recognition Agreement. Every Traceable® product undergoes an intense vetting process before it can carry the Traceable name, saving you both time and money by eliminating the need for separate calibration.
