Air flow testing system C190H

gas permeabilitypermeabilitycompressed air

The C190H Air Permeability Tester is a laboratory instrument that applies the volume method to measure gas permeability of battery diaphragms, breathable membranes, related polymer materials, cigarette paper and various papers. It provides fully-automatic, high-precision measurement with flexible three-cell testing and intelligent control for reliable, repeatable results.

Product Features

• Volume Method, Fully-automatic & Highly Precise: gas volume passing through the specimen is fully automatically determined (replaces manual sliding-cylinder measurement); pressure control accuracy better than 0.01 kPa; test pressure can be set freely via software.
• Three-cell Design, Flexible & Efficient: three independent testing cells allow testing of three specimens in a single run; selectable three-cell independent test or three-cell joint test; fast test mode reduces total test time for three cells to approximately 1 minute.
• Automatic Specimen Clamping, Safe & Labor-saving: pneumatic specimen clamping provides consistent clamping force and improved sealing; anti-pinch design for safer operation.
• Intelligent Control, Convenient & Reliable: 12-inch Windows tablet supplied for convenient control; embedded Labthink industrial computer to reduce system failures and ensure data storage security; core sensor and pneumatic control from well-known manufacturers for long service life and low failure rate; automatic detection and recording of test temperature and humidity; supports multi-unit display (e.g., s/100 mL and μm/(Pa·s)); optional software functions include multi-level authority management and audit tracking.

Test Principle
In the test temperature, humidity and atmospheric pressure, the instrument measures the time required for 100 mL of air to pass through a diaphragm with an area of 6.45 cm2 under a pressure of 1.21 kPa.
