(China)YY461E Automatic Air Permeability Tester
Used for testing air permeability of industrial fabrics, nonwovens, coated fabrics and other industrial paper (air filter paper, cement bag paper, industrial filter paper), leather, plastics and chemical products which need to be controlled.
GB/T5453、GB/T13764，ISO 9237、EN ISO 7231、AFNOR G07，ASTM D737，BS5636，DIN 53887，EDANA 140.1，JIS L1096，TAPPIT251.
1.By the large screen color touch screen control test alone, can also be used for computer control test, the computer can display the dynamic curve of pressure difference - air permeability in real time, easy to control the quality of the product, so that the R & D personnel more intuitive understanding of the sample permeability performance;
2.The use of high-precision imported micro-pressure sensor, the measurement results are accurate, good repeatability, and foreign brands to do data comparison error is very small, obviously better than the domestic peer production of related products;
3.Fully automatic measurement, the sample is placed in the specified position, the instrument automatically looks for the appropriate measurement range, automatic adjustment, accurate measurement.
4. Gas clamping sample, fully meet the clamping requirements of various materials;
5.The instrument adopts the self-designed silencing device to control the suction fan, to solve the problem of similar products due to large pressure difference and large noise;
6.The instrument is equipped with standard calibration orifice, which can quickly complete calibration, to ensure the accuracy of data;
7. The use of long arm clamp handle, can measure the larger sample, without having to cut the large sample small, greatly improve the work efficiency;
8. Special aluminum sample table, the whole shell metal baking paint process processing, durable machine appearance beautiful and generous, easy to clean;
9.The instrument is very simple operation, Chinese and English interface is interchangeable, even inexperienced personnel can operate freely;
10. Test Method:
Fast test (single test time is less than 30 seconds, fast results);
Stable test (the exhaust speed of the fan increases at a uniform speed, reaches the set pressure difference, and maintains the pressure for a certain time to get the result, which is very suitable for some fabrics with relatively small air permeability to complete high-precision test).
1. Sample holding method: pneumatic holding, manually press the clamping device to automatically start the test.
