Desk stand, wall-mounting screws, batteries, and NIST-traceable calibration certificate with data.

The atomic clock automatically sets correct time and date 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). Simultaneously displays relative humidity along with both ambient and remote temperature for easy comparison of room temperature versus outdoor temperature.
Signal reception includes four strength levels; RC synchronize process, weak signal quality, acceptable signal quality, and excellent signal quality. The weather forecast indicator includes; sunny, slightly cloudy, cloudy, and rainy along with ice alert when outdoor temperature falls between -2 and 3°C.
Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that 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. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

Traceable Large Digit Radio Atomic Clock with Ambient and Remote Temperature and Humidity does not show the day and date, but instead includes humidity from 20 to 90%.
