With the development of electronic scales and the needs of special applications, the waterproofness of electronic scales has gradually been valued by consumers and manufacturers, and there are certain differences in waterproof performance of electronic scales due to different waterproof levels.In order to obtain the highest waterproof performance of electronic scales, manufacturers will conduct waterproof testing of electronic scales.However, due to the structural differences of electronic scales, the corresponding detection methods are also different, which is also one of the difficulties in testing the waterproofness of electronic scales.

  As an expert in waterproofing testing and a developer of waterproofing testing equipment, Hairis Technology also has specialized research on waterproofing testing of electronic scales.So, this time we will share a waterproof testing case of an electronic scale for your reference.

Hairis Technology Electronic Scale Waterproof Tester

1. The appearance and detection difficulties of electronic scales

1. The shape of the electronic scale is a rectangular parallelepiped with rounded corners. There is an electronic display on the front of the electronic scale, and a protruding irregular cylindrical weighing plate on the top. The irregular shape is not conducive to direct waterproof testing of the instrument;

2. The appearance of the electronic scale is wrapped and sealed with waterproof materials. If the sealing is not strong enough, the waterproofness can be tested through internal gas supply;

2. Breakthrough in the difficulty of waterproofing testing of electronic scales

1. Corresponding to the characteristics of the electronic scale, Hairis Technology has customized a special mold for this electronic scale. The mold corresponds to the appearance characteristics of the electronic scale and has a special groove for placing the scale pan. The electronic scale is placed in the mold and stuck just right, which facilitates the mold to close up and down during inspection;

3. For the waterproof structure of the electronic scale, we cannot use direct detection methods to directly test its waterproofness. The use of a mold can not only close it up and down during testing, forming a closed state on all sides, but also avoid leaks when inflating the inner body during testing. The gas filled in the mold uses compressed air as the testing medium, and the mold is directly inflated. Without liquid testing, unnecessary damage to the electronic scale can be avoided.

2. Display and parameter list of electronic scale waterproofness tester

1. High-sensitivity pressure sensing and adjustment unit, combined with advanced differential pressure software algorithm, the minimum resolution can reach 0.1Pa. This algorithm has obtained a national patent;

2. Patented technology independently developed by Hairuisi,"IVT pneumatic sealing valve island", greatly improving the test accuracy, ensuring the stability of the instrument, and the inflation speed is also greatly improved;

3. Multiple test functions: The instrument integrates two pressure forms, positive and negative, and 8 test methods: two pressure forms and five test methods can be programmed into more than 20 test functions;

4. It has more than 200 groups of subroutines. Each group of subroutines can be programmed independently, single selected and combined to meet various complex testing requirements;

5. Full-touch large-screen intelligent operating system, graphical UI design based on the detection process, the operation interface is simple and clear, easy to teach and learn;

6. A variety of pressure adjustment components and ranges are optional, with a wide air pressure range (-80KPA&-1MPa) optional.The optional electronic pressure regulating valve can realize multiple sets of pressure sequential tests;

7. Multiple communication interfaces: built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supporting multiple communication protocols;

8. Optional barcode scanning function and printer are available to facilitate product data management and quality traceability. The instrument history record can reach up to 200,000 items and can be exported to the computer in batches;

9. The standard volume identification function can automatically identify the volume of the sample to be tested, and measure and judge the leakage rate in a volumetric manner;

10. Ultra-high stability and ease of use, which have passed the rigorous test of the market;

11. A variety of accessories are available, including inflatable bypass, quick connector, and standard leak hole. At the same time, the instrument supports third-party calibration and can issue a calibration report.
