Mil-spec computers have been developed to be used in very challenging rugged environments. These industrial embedded PCs consist of carefully selected internal and external ultra-rugged components. The Mil-Spec hardware has therefore been extensively tested to meet the CE, MIL-STD810, MIL-STD704F and MIL-STD 1275D standards. Mil-Spec PCs are sometimes also referred to as Rugged COTS (Custom Off The Shelf) and are specially developed to be exposed to debris, extreme temperatures, shocks & vibrations and in most cases to moisture. Such rugged COTS are deployed at remote rugged locations, where one depends on consistent operation and minimal downtime. For example, offshore rigs, oil and gas pipeline monitoring facilities, heavy construction equipment and space integrators all use Mil-Spec computers to monitor and control critical equipment.
