YG463 Wang Yanfa Permeability Tester

• YG463 Wang Yanfa Permeability Tester

  Instrument use:
  It is applicable to the determination of the permeability of the separator of lithium ion batteries.
  Measuring principle:
  When air at a certain pressure passes through the air nozzle, the resistance of the test piece to air penetration determines the air pressure between the air nozzle and the test piece. Determine the pressure value and theoretically calculate the permeability value equivalent to the number of isolation seconds.
  Product features:
  1. The inlet pressure is reduced by the swagelok pressure reducing valve imported from the United States, which effectively protects the safety of some devices tested;
  2. The test pressure control adopts the BELLOFRAM precision pressure regulating valve imported from the United States, with high control accuracy;
  3. Adopt high-precision pressure transmitter to collect the test pressure, feedback the test pressure in real time, and respond sensitively;
  4. The whole machine is equipped with a large-capacity buffer cylinder to avoid pressure fluctuation caused by sample leakage;
  5. The dual-station design can meet the test of samples with different widths;
  6. The heat flow mass flowmeter with higher stability is used to monitor the air leakage of the sample;
  7. The installation method of the sample conforms to ergonomics and is easy to install;
  8. The double clamping surface of the sample is made of 40Cr special steel, which is quenched and then grinded, and then matched with the sealing device to ensure that the sample fits tightly without air leakage;
  9. The sample is clamped pneumatically;
  10. Large screen color touch screen, Chinese and English interface, menu-type operation mode;
  11. It is equipped with a printer interface, which can directly print data reports when connected to a printer;
  12. The equipment is equipped with online software, which can transmit data through the PC serial port. The test data can be automatically and immediately transmitted to the PC end for display in the special software, and can be exported to CSV (Excel) format (which can be used for secondary development, including uploading MES);
  13.Instrument calibration: the instrument has its own standard device, which is convenient for daily calibration;
