When looking for scanning equipment for everyday use in the company, we pay attention not only to its technical parameters, allowing to increase efficiency and comfort of use. We also care about the safety of the selected device, its strength and resistance to mechanical damage and the penetration of substances inside. For this, a special classification is used.
The first digit after the IP prefix specifies protection against the ingress of solid objects, mainly dust or dirt, and is presented on a scale from 0 to 6. The second digit after the IP specifies the level of waterproofing and informs the user about degree of protection against ingress of liquids on a scale from 0 to 9. The rule is that the higher the IP number, the more effective the protection of the equipment.
The first digit - solids
The table below shows the level of protection against the ingress of solid objects (dust, dirt, etc.)
| The first digit after the IP code | Description |
| 0 | without protection |
