IP er den engelske Ingress Protection, hvilket betyder forkortelsen af de to første bogstaver i beskyttelsesniveauet. Inden for elektronisk udstyr udtrykker det beskyttelsesniveauet for elektronisk udstyr mod indtrængen af fremmedlegemer. I de følgende to arabiske tal udtrykker det første tal niveauet af støvtæthed, og det andet tal udtrykker niveauet af vandtæthed. Jo større tal, jo bedre effekt af beskyttelse.
So the protection grade is IP65 industrial panel computer, which means that it can completely prevent dust from entering, and the low-pressure water jet at any angle cannot affect the industrial panel computer.
In other words, this level of industrial tablet computers can work normally in dusty environments, even in humidity environments, and even in light rain environments.

0: No protection
1: Prevent the intrusion of large solids
2: Prevent the intrusion of medium-sized solids
3: Prevent the intrusion of small solids
4: Prevent solids larger than 1mm from entering
5: Prevent the accumulation of harmful dust
6: completely prevent dust from entering
Waterproof rating (the meaning of the second number)
0: No protection
1: Water droplets into the shell have no effect
2: Water or rain dripping onto the shell from an angle of 15 degrees has no effect
3: Water or rain dripping onto the shell from a 60 degree angle has no effect
4: Water splashing from any angle has no effect
5: Low pressure injection at any angle has no effect
6: High-pressure jet water has no effect
7: Can be immersed in a short time (375px-1m, within half an hour)
8: Long-term immersion in water under certain pressure
