Understand the dust and water proof standard of the instrument in one article
01. What is IP protection?
IP protection: a protection measure for electronic equipment, which is used to prevent external substances (such as water, dust, etc.) from entering the equipment, so as to protect the normal operation of the equipment.
02. IP protection level standard
IP protection level is a standard formulated by IEC (International Electrotechnical Commission), which is used to evaluate the protection ability of electrical equipment against dust and water.
The IP protection level consists of two numbers: the first number indicates the dust-proof level, and the second number indicates the waterproof level. Generally speaking, the higher the number, the better the protection performance.
After understanding the above standards, you can understand the meaning of common IP protection levels.
| Dust Protection Standard (X - first digit) | Water Protection Standard (X - second digit) |
| 0: No dust protection | 0: No water protection |
| 1: Prevents solid objects larger than 50mm from entering | 1: Prevents water droplets from entering when falling vertically |
| 2: Prevents solid objects larger than 12mm from entering | 2: Prevents water from entering when tilted at 15 degrees |
| 3: Prevents solid objects larger than 2.5mm from entering | 3: Prevents spraying water with an angle of up to 60 degrees from entering |
| 4: Prevents solid objects larger than 1mm from entering | 4: Prevents water from any direction |
| 5: Prevents harmful dust from entering | 5: Prevents low - pressure water jets from any direction |
| 6: Completely dust - tight | 6: Prevents high - pressure water jets from any direction |
|
| 7: Can be submerged in water and still function properly, and can operate underwater |
|
| 8: Can withstand continuous immersion in water under conditions specified by the manufacturer |
|
| Can withstand high-pressure and high-temperature steam cleaning while ensuring that the sealing materials and materials used do not cause harmful effects |
CAATM electronic products have high protection level
At CAATM, all products have to undergo rigorous tests and can only be circulated in the market after all performances reach the standard. In terms of the waterproof and dustproof ability of instruments, CAATM electronics insists that all products have a high protection level, and the protection level of some instruments can reach IP66, which is far higher than the requirements of the national standard.
CAATM electronics adheres to the production guidelines of high standards and strict requirements, so that users can enjoy "safer and more professional" product services, make good use of products and good services, and build a solid foundation for gas environment safety!
