Perfect for smartphone-sized work! A waterproof tester with excellent low-pressure characteristics. Custom orders and modifications are also available.
The "WPC6220P002/A/WO" is a waterproof mobile phone leak tester that employs a strain detection method. The work holder uses a contact pin connection method and has a maximum measurement pressure of 20 kPa (equivalent to a water depth of 2 meters). It excels in pressure resolution under low pressure, making it ideal for airtight waterproof testing of waterproof mobile devices and multi-chamber structural components. Since it can be set in 1 kPa steps, it can stably detect leaks at optimal test pressures even for workpieces that are prone to deformation due to pressure. 【Features】 ○ Standard equipped with an automatic opening and closing mechanism for the pressurization capsule ○ Safety mechanism with area sensors ○ Two circuits of strain sensors installed inside the capsule ○ Ideal for airtight waterproof testing of smartphone-sized devices ○ Capable of testing two units simultaneously For more details, please contact us or download the catalog.

Company information
We design, develop, manufacture, and sell waterproof testing equipment used in the automotive industry, watch and electronics industry, medical and food industry, mobile phones, smartphones, and portable devices, among others. Since its establishment in 1973, Hamron Tech Co., Ltd. has consistently developed, manufactured, and sold leak testing devices. In particular, the "WPC series" of airtight waterproof performance testers, which employs the "strain detection method," is a technology invented and uniquely developed by our company. It is a groundbreaking product with numerous excellent features as an airtight waterproof performance tester for small sealed items, adopted by all Japanese watch manufacturers. We have secured over 90% domestic market share among waterproof mobile phone and smartphone manufacturers, and we have a significant track record of deliveries to overseas manufacturers, making it a de facto industry standard model. It is also used for testing various products such as waterproof digital cameras, video cameras, and televisions, with cumulative shipments of the WPC series exceeding 6,000 units. We aspire to be a solution planner for our customers' various "leak" related issues. As of October 1, 2023, we have transferred our business to our parent company, Rika Aihara Seiki Co., Ltd. Going forward, Rika Aihara Seiki will handle the sales and maintenance of Hamron products.
