If you have ever used electronic measuring tools such as calipers or micrometers, you must have seen symbols such as IP54, IP65 or IP67 printed on the body of the device. For example, the Mitutoyo 293-340-30 micrometer model comes with an IP65 index. These symbols are not product codes or measurement parameters, but an important standard directly related to the durability and working ability of the device in real environments.
