PISKEKAT Server Rack 12.5 Inch Atomic Clock with Temp Humidity

SKU CH-E932-W7AZ6

A 12.5 inch atomic clock that auto-sets via NIST radio signal, displays indoor temperature and humidity, and includes an alarm function

  • TypeServer
  • Automatic time sync via NIST radio signals
  • Battery powered with alarm function using 3 AA cells
  • Indoor temperature and humidity monitoring included
  • Large 12.5 inch display with clear digits for easy reading
  • Supports 12 or 24 hour format and four time zones

12.5 Inch Atomic Wall Clock

This 12.5 inch atomic clock receives NIST radio signals to set the correct time automatically and adjusts for Daylight Saving Time when enabled. It displays indoor temperature and humidity alongside the date, day and seconds in a large digital format. The unit operates on three AA batteries and can be mounted on a wall or placed on a desk.

Continuous NIST Time Sync

Under sustained use the clock maintains accuracy by regularly syncing to the Colorado broadcast signal so the displayed time does not drift. Battery power keeps the display and sensors running without mains wiring, while the lack of a backlight reduces ongoing energy draw. Temperature and humidity readings update continuously to reflect current room conditions.

Replaces Manual Set Clocks

This unit replaces clocks that require manual time setting and separate thermometers or hygrometers. The jump is worth it when you need a single device that keeps precise time without intervention and shows environmental data at a glance. It is not for buyers who need a backlit display for dark rooms or who want smart home connectivity and data logging.

Questions about this item

Does the 12.5 Inch Atomic Clock generate any noise, heat or measurable power draw when running continuously?

The clock runs silently on three AA batteries with no fan or mains supply, so it produces no audible noise, no perceptible heat and negligible power consumption during all-day operation.

What must I already own for the 12.5 Inch Atomic Clock to function out of the box?

You need three AA long-life batteries, which are not included, and a location where the NIST WWVB radio signal from Colorado can be received for automatic time setting.

Will the 12.5 Inch Atomic Clock interfere with or depend on older radio-controlled clocks or weather stations I keep nearby?

It operates as a receive-only device on the WWVB frequency, so it neither transmits nor conflicts with other atomic clocks, weather sensors or legacy radio-controlled equipment in the same room.
