Asahi Seiko Wang Yan style air permeability meter, calibration tools, and calibration methods from Japan!

• Validate test materials

• Before measurement, use a spray gun or brush to remove foreign particles from the test material. Tiny dust may cause measurement errors.
• When the test material is inserted into the measuring position (the opening below the measuring head), ensure that the measuring side of the test material is downward, while the other side may have different test results depending on the quality of the material.

• If the permeability measurement pressure cannot reach 500 mmH₂O.

Rubber ring degradation or pipeline leakage may cause this problem. Please.

• routine maintenance

• Verify 500 mmH₂O

Ensure that the permeability measurement pressure reaches 500 mmH₂OFor specific reference details, please refer to section 3 of section 8

• Check with reference nozzle

Connect the reference nozzle sold separately to the output section of the tester to check its accuracy.

For detailed information, please refer to the material 'How to Use Reference Nozzles'.
