IP67 waterproof refers to a 6-level dustproof and 7-level waterproof capability. IP67 level certification equipment can protect dust from entering (overall prevention of contact, protection of dust penetration), while protecting liquid immersion (anti-immersion), in water up to 1 meter deep can have a maximum of 30 minutes of anti-immersion capacity. SDA Shangda waterproof ventilation valve protection grade up to IP67 IP68 grade.

specific introduction is as follows:

1. IP67 refers to the protection safety level, of which ip refers to the abbreviation of Ingress Protection Rating, which is a dustproof and waterproof grade standard drafted by the International Electrotechnical Commission;

2. There are two digits after IP67. The first is solid protection level, ranging from 0 to 6. The lowest is no special protection for external people or objects, and the highest is to completely prevent foreign objects and dust from invading. The second is the liquid protection level, ranging from 0 to 8. The lowest 0 means there is no special protection against water or moisture.
