8. What is IP? IP stands for Ingress Protection.
The IP rating tells you how resistant a mechanical casing or electric enclosure is to dust particles and liquids entering the electronics of the device.
An IP rating gives an idea of how vulnerable the product is to contamination and damage caused by solids and liquids getting into the unit.
The SR500 has an IP rating of 67. The first digit signifies particles, and the second digit signifies liquids.
