There's always that moment of irrational hope just as disaster strikes a personal electronic device. Maybe your cell phone will be the first ever to survive an accidental bath, or perhaps your laptop, tumbling off the table, won't shatter. The good news? If your device has a high Ingress Protection (IP) rating, it just might tough it out. The IP uses a two-digit system: The first digit (from 0 to 6) measures protection against solid objects like hands, wires and dust; the second (from 0 to 8) measures the level of protection against liquids, from condensation to total immersion.
