Most customers ask Sailham about IP66 and IP67 testing machines, few people knew that IP66 and IP67 include two separate tests for dust and water resistance, requiring two independent machines. The first number after the IP represents the dust resistance level, and the second number represents the water resistance level. That is to say, IP67 consists of an IP6X dustproof test chamber and an IPX7 waterproof test chamber.
