ESE ES-942 Wall Mount Digital Clock, 4 Inch Display

The ES-942 is a stand-alone wall clock for facilities that do not need GPS or temperature-controlled accuracy, showing time on a 4 inch red LED display legible from as far as 120 feet, which is what a studio floor or a warehouse wall calls for. AC line frequency serves as the standard time reference, with an optional quartz crystal timebase for locations where the power line drifts.

Fast, Slow and Hold controls on top of the case handle time adjustment, it runs on 110-120 VAC standard with a 220-240 VAC option, and UL-certified versions are available. A 24-hour version, the ES-944, is offered for military-time facilities.
