Product Description

Product FeaturesNote1

Two measurement methods of constant pressure difference and constant flow can be freely selected.
High precision electronic air flow and air pressure sensors ensure the accuracy of test data.
Built-in imported maintenance-free vacuum pump system for better airflow stability.
Professional sample fixture for safer operation.
Pneumatic clamping of the sample saves time and labor, and the clamping force is consistent.
7" color industrial touch screen & desktop operating system are for simple and convenient operations.
The system has built-in calendar, multi-language switching & multi-level authority management, etc.
Needle micro printer is connectable for the output of test results, and the results can be stored for a long time (optional).
Standard RS232 interface facilitates the connection between the system and computer and data transmission (optional)

Test Principle

Method A:the air flow is stabilized vertically through the sample at a constant flow. Then, the pressure difference formed on both sides of the sample is measured under this condition, and air flow resistance and other parameters are calculated.

Method B:through adjustment, a constant pressure difference is formed on both sides of the sample, the air flow passing vertically through the given area of the sample in a certain time is measured, and the air permeability and other parameters are calculated.

Standard

ISO 9237, ISO 4638, ISO 5636, GB/T 10655, GB/T 5453, GB/T 4689.22, GB/T 13764, ASTM D737, TAPPI T460, JIS P8117
