Water Vapor Transmission Rate Tester YG501F-II

Instrument Usage:

The principle of the weighing method of the breathable cup is to measure the transmittance of water vapor to films, sheets, papers and other materials by weighing the weight of the breathable cup.

Standards: YY/T0471.2-2004。

Features:

• Large-screen color touch screen, Chinese and English menu operation interface;
• The standard test environment module and the moisture permeability test module are designed separately, and the internal wind speed of the box will not affect the moisture permeability test module, and the temperature and humidity are more uniform;
• The standard test environment module can be used as a constant temperature and humidity chamber alone;
• The standard test environment module meets the standard requirements, and the specified temperature and humidity are re-reached within 3 minutes after the door is closed;
• The moisture permeability test module is equipped with a special air duct and a frequency conversion control mode to make the wind speed, temperature and humidity more stable;
• The moisture permeability test module is equipped with a high-precision wind speed sensor to monitor the wind speed of the test air duct;
• The equipment can not only use the desiccant placed in the test cup to control the external humidity for weight gain test, but also test the water in the cup to control the external humidity for weight reduction experiment
• The equipment meets the requirements of the standard for batch weighing, with an automatic intermittent weighing test mechanism, and the weight sensor can be automatically cleared during the test
• Rotating sample holder, sample testing effect is more uniform;
• Refrigeration system: the original imported French “Taikang” refrigeration unit to ensure the long-term stable operation of the whole machine;
