DRK461D air permeability tester
DRK461D air permeability tester is used to determine the air permeability of various woven fabrics, knitted fabrics, non-woven fabrics, coated fabrics, industrial filter materials and other air-permeable leather, plastic, industrial paper and other chemical products.
product details
Standards Compliant:
GB/T5453, GB/T13764, ISO 9237, EN ISO 7231, AFNOR G07, ASTM D737, BS5636, DIN 53887, EDANA 140.1, JIS L1096, TAPPIT251 and other standards.
Features:
1. Using high-precision micro differential pressure sensor, the measurement result is accurate and the repeatability is good.
2. Large-screen color touch screen display operation, menu operation in Chinese and English interface.
3. The instrument uses a self-designed muffler device to control the suction fan, which solves the problem of large noise due to large pressure difference of similar products.
4. The instrument is equipped with a standard calibration orifice plate, which can quickly complete the calibration to ensure the accuracy of the data.
5. Test method: quick test (a single test time is less than 30 seconds, and the result can be obtained quickly).
6. Stability test (the fan’s exhaust speed increases uniformly, reaches the set pressure difference, and keeps the pressure for a certain period of time to get the result, which is very suitable for some fabrics with relatively small air permeability to complete high-precision testing).
7. According to the test prompt, manually replace the test orifice plate.
8. The sample adopts manual clamping device.
