As an electronic product that is both beautiful and practical, smart watches have always been favored by people. At the same time, because they are often worn on the hands, they will inevitably come into contact with water, so the waterproof performance of smart watches has always attracted people's attention.along withThe requirements for waterproof performance of 5ATM smart watches are gradually increasing, and many manufacturers have begun to pay attention to the waterproof testing of 5ATM smart watches.Today we will discuss how 5ATM smart watches perform waterproof testing.

We often see water resistant or WR 5ATM written on the back of some watches. ATM is the abbreviation of atmospheric pressure. An ATM is equivalent to 10 meters of water depth, and 5ATM is 50 meters of water depth.What needs to be explained here is that 5ATM waterproof isThe waterproofing of this component is required to meet the atmospheric pressure waterproofing level of 5ATM.,andIt’s not like diving 50 meters into the sea without taking in water.30 meters (3ATM, 3 atmospheres)waterproof watch, can be used for daily grooming or use in the rain, that is, water droplets only splash on the surface without any water pressure on the watch.50 meterswaterproof watchIt can be used for swimming and general housework. The 100-meter waterproof watch can be used for underwater work such as swimming and diving.

In the process of producing waterproof watches, the last step before packaging is to test the watches for waterproofing. Nowadays, many manufacturers use this method.Waterproof testerTest the waterproof performance of the watch.The detection medium used in waterproof testing equipment is compressed air. Because air molecules are smaller than water molecules, the detection results are more accurate. Moreover, the sensors of the waterproof testing equipment observe the detection status of the product in real time and the test data is intuitively displayed on the air tightness detector. It is easier for the inspector to intuitively understand the waterproof performance of the product.

Different waterproof properties require different test data. For example, some watches are 3ATM waterproof, which is 30 meters waterproof. The test pressure we use is 300KPA.Some watches are 5ATM, so our test pressure is 500KPA. The test pressure is set according to the product and waterproof performance.Hai RuisiWaterproof testerThere are various ranges, including -60-150kpa for low-pressure testing of small products and 50-1500KPA for high-pressure testing.The lower the measuring range, the higher the accuracy. The measuring range accuracy of Hirays Technology's instruments is generally higher than 1PA. This accuracy is based on national patented technology.
