BRG Precision Products
BRG has been in the precision clock business since 1998 and we are pleased to feature their DuraTime HP clocks.
First offered in 2014, the DuraTime HP clocks use oven-controlled crystal oscillators (OCXO) that are factory synchronized with the U.S. atomic clock. These clocks are 10,000 times more accurate than consumer clocks and do not need to be further adjusted for up to 20 years. Just plug them in, add leap seconds when necessary, and that should just about do it for the next two decades.
All DuraTime HP clocks plug in to wall power, so there are no batteries to change.
