Both ratings ensure complete protection against solids.
Due to this they are both fully covered against dust, sand and dirt. Furthermore, both IP67 and IP68 ratings offer excellent protection against splashes.
On the other hand, what defines the difference between the two, it’s the submersion in water.
The resistance to water is defined by the manufacturer that set the conditions for IP67 and IP68.
RugGear devices with IP67 rating can be fully submerged in fresh water to a depth of 0.5m, for 30 minutes.
So with the higher IP68 rating, the device has even more protection, allowing it to be submerged to a depth of 1.5m for up to one hour.
Note that this guarantee applies only to non-corrosive liquids, such as fresh water and salt water.
A key benefit of this is the increased strength of the phones, able to survive the most challenging situations.
