- Digital Wall Clock - Accurate for 20 Years - Four 4-Inch Blue Digits
The DuraTime HP440B is a high precision plug-in digital wall clock with a 4-digit 4-inch high blue LED display (12 or 24 hour format) and shatterproof polycarbonate lens. These come standard in a tough ABS plastic case but may be upgraded to a black aluminum case. For extra rough-and-tumble environments like high-traffic hallways or locker rooms, consider adding an optional Lexan clock guard.
Thanks to the oven-controlled crystal oscillator (OCXO), once configured, this clock won't need to be adjusted again for 20 years, except to add the occasional leap second using a firmware update from BRG (future leap seconds known at the time of purchase will be pre-programmed at the factory).
All DuraTime HP clocks are factory-synchronized with the U.S. atomic clock and pre-programmed to your local time zone and DST requirements based on the shipping address or the time zone information specified in the purchase options. The time zone and time format are user-changeable using buttons on the back of the clock.
Here are few more key points about all DuraTime HP digital clocks:
BRG's DuraTime HP clocks are powerful, precision instruments, designed to provide highly accurate time with no battery changes, no Daylight Saving Time adjustments, no master clocks, no radio signals, and no maintenance other than the rare leap second addition.
BRG Precision Products, Inc. warrants the product against defects in workmanship and materials for one year. For full details, please see the BRG Warranty at BRGPrecision.com.
