This is an ultra-rugged water- and dust-proof mobile PC suitable for the physically demanding fieldwork done by police officers or checking and maintenance by road service or gas companies. It can be safely dropped from a height of 1.2 m. The PC incorporates a low-power-consumption CPU, a long-life battery, and a wide-area radio antenna that makes it easy to connect to a network. It is suitable for right- and left-handed users. Provided with a rotary strap to reduce strain on the wrists. You can easily type while wearing gloves thanks to the positioning of commonly used keys that can be pressed by thumbs and staggered key arrays.
