There are many different watches on the market, children's smart watches, mechanical watches, and outdoor sports watches.With the development of modern technology, many smart watches not only have ordinary watch timing functions, but can also be connected to WeChat to realize instant call functions; sports watches can not only time time, but also serve as heart rate monitors to monitor the user's heart rate changes during exercise.

With the increase of watch functions, in order to protect the watch and increase its service life, more and more watches need to be waterproof, so the watch needs to be waterproof.Waterproof testis an essential step.

Watches with waterproof functions have various waterproof levels, including IP67 waterproof watches, 3ATM waterproof watches, and 5ATM waterproof watches.Watches with different waterproof levels use different test pressures.For IP67 waterproof watches, the test pressure is generally 10.5kpa, which is equivalent to the pressure of the product in one meter of water.For 3ATM waterproof watches, a test pressure of 300kpa is generally used for testing; for 5ATM waterproof watches, a test pressure of 500kpa is generally used.

For waterproof testing of smart watches, the current mainstream waterproof testing method is to use compressed air for air tightness testing.Compressed air is a colorless and odorless air. Because air molecules are smaller than water molecules, it can detect product leaks with higher accuracy.At the same time, compressed air will not cause secondary damage to the test products, especially some electronic products such as watches. Electronic components will suffer irreparable damage when exposed to water.Therefore, the air tightness detector has many advantages over the traditional method of detecting leaks with water.

For air tightness testing of various types of watches, the testing steps are generally divided into three steps: filling the corresponding test pressure - pressure holding stage - testing stage
