YS-461K-III Computerized Air Permeability Tester for Paper and Paperboard
Applicable Scope:
This air permeability tester features a modular design and complies with various standards and testing methods, including Schopper, Gurley, and Bendtsen. It offers optional ranges, different measurement areas, automatic reading, and automatic calculation of air permeability.
Test Principle:
The equipment automatically adjusts to the set pressure difference and automatically reads the gas flow rate once the pressure difference is stable.
Compliance Standards:
QB/T 1667-98 "Air permeability tester for paper and paperboard"
GB/T 458-2008 "Paper and board - Determination of air permeance"
ISO 5636-2:1984; ISO 5636-5:2003; ISO 5636-3:1992
ISO 5636/5, TAPPI T46, SCAN-P19, SCAN-P60, SCAN-P8, ISO 5636/3, DIN 52120, TAPPI T54, ISO 5636-4
Instrument Features:
Fully automatic testing with a short test duration and simple one-touch operation.
Modular design with multiple configurations available, truly achieving multi-functionality in one machine.
7-inch touch screen displaying test results in various units, with the ability to print results.
Uses imported high-precision flow meters and pressure sensors for high testing accuracy and excellent repeatability.
Features result judgment; automatically determines whether the result is within the set acceptable range.
