Daily life, breathable word with our lives, summer clothes to wear breathable, so as to keep themselves in a relatively cool state; sleep at night, the room should be breathable, feel or sleep at night more boring; usually wear shoes should be breathable, otherwise it is easy to produce sweat. We can say that people feel comfortable to be guaranteed, it must keep themselves in a breathable environment.
      In our textile industry, breathable or not there is a specialized terminology to describe this jargon is the amount of ventilation air permeability refers to the unit at a constant temperature and pressure difference in the gas penetration is stable unit time through through the sample gas volume per unit area, common units cm3 / m2 · d · atm. By definition analysis, ISO 2556 standard defines the Gas trans-mission rate also consistent with the amount of ventilation. Another characterization of material properties and permeability coefficient (gas permeability coefficient) is the amount of breathable film thickness (the thickness of the sample is detected value) of the product.
      Life used to test the amount of ventilation equipment, there are many, of which, Changzhou Shuanggudunda Electromechanical Technology Co., Ltd. R & D production SG461-III-type digital air permeability testeris such a professional measuring instrument, it is mainly used to test a variety of print materials, such as: knitted, woven fabrics (including close coated fabrics), nonwovens, paper, paper blankets, fiberglass, foam air filter and other materials, permeability, and its fast, accurate test.
      SG461-III-type digital air permeability tester design, stylish appearance, the operation is also very convenient; it is high precision, Taiwan is small, in line with a variety of international and domestic standards. Once launched, by the market customers.
      Instrument features:
      1, can accurately detect various permeability properties of the sample, the difference between a small table, high precision.
      2, easy to operate, greatly reduces test time.
      3, touch-screen control, Chinese Pinyin input more intuitive.
      4, a friendly interactive interface, clear, allowing users to quickly master the operation.
      5, data port: You can connect an external memory card, export data, do not worry about data loss.
      6, test results evaluation system, automatically calculate and print output.
