We took a fully functional touchscreen PC, submerged it in a puddle of muck, then hosed it off, all while plugged in and running.. because we could.
This computer (Glacier – S9000) is made for food processing operations, outdoor kiosks, farms, or any any indoor or outdoor application, fixed or mobile, AC or DC power, anywhere you might want a shiny stainless steel unit you can hose off whenever you think it’s gotten too dirty.
