C190H Air Permeability Tester

Product Description

Product Features

Volume Method, Fully-automatic & Highly Precise

• Gas volume passing through the specimen is fully-automatically determined, replacing the traditional manual sliding cylinder gas volume measurement method.
• Fully-automatic high-precision pressure control technology; the pressure accuracy is better than 0.01kPa.
• Test pressure can be set freely by software.

Three-cell Design, Flexible & Efficient

• Three-testing-cell design can accomplish tests for threes specimens in a single test.
• Three-cell independent test and three-cell joint test can be selected freely.
• Fast test mode is provided, and the total test time of three cells is reduced to 1 minute.

Automatic Specimen Clamping, Safe & Labor-saving

• Pneumatic specimen clamping saves time and labor, with consistent clamping force and better sealing.
• Pinch-proof design and safe operation.

Intelligent Control, Convenient and Reliable

• 12 inch tablet of Windows system is installed for more convenient control.
• Embedded unique high-end Labthink industrial computer eliminates system failures caused by computer viruses and ensures operation reliability and data storage security.
• Core sensor and pneumatic control system are from world-renowned manufacturers, with low failure rate and long service life.
• Automatic detection of temperature and humidity of test environment; automatic record of the test conditions.
• The instrument supports multi unit display, such as s/100 mL and um/(Pa.s), which is applicable to the detection requirements of different standards.
• Software has functions such as multi-level authorization management and audit tracking (Optional).

Test Principle

In the test temperature, humidity and atmospheric pressure, the instrument tests the time required for 100mL air passing through the diaphragm with an area of 6.45cm2 under the pressure of 1.21kPa.
