FAQs

1. What is the purpose of this Water Vapour Permeability Tester?

Water Vapour Permeability Tester is designed to measure the rate at which water vapor passes through barrier materials such as plastic films, aluminum films, sheets, and rubber sheets. This is essential for industries like food packaging, pharmaceuticals, electronics, and solar energy, where moisture protection is crucial. Using an infrared moisture sensor, the device provides precise and repeatable measurements to ensure materials meet required barrier performance standards.

2. How does the Water Vapour Permeability Tester work?

Water Vapour Permeability Tester functions by placing a test sample between two chambers, with one side exposed to a humid environment and the other side to dry nitrogen gas. Due to the humidity difference, water vapor moves through the sample and is carried by the nitrogen gas to an infrared moisture sensor. The sensor detects changes in water vapor concentration, and the device calculates the transmission rate based on the difference in moisture levels.

3. What types of materials can be tested with this Water Vapour Permeability Tester?

This Water Vapour Permeability Tester can test a variety of materials, including plastic films, co-extruded films, aluminum composite films, sheets, metal foil sheets, and rubber sheets. These materials are commonly used in food and pharmaceutical packaging, solar panel encapsulation, and electronics protection, where moisture barrier properties are critical.

4. Does the Water Vapour Permeability Tester have automatic control features?

Yes, the Water Vapour Permeability Tester features intelligent automation for user-friendly operation. It comes with a 10.1-inch touchscreen interface, making it easy to input test parameters, monitor test progress, and access results. The system supports automatic temperature and humidity control, reducing the need for manual adjustments. Additionally, it includes one-click access to test data, alarms, and system settings, ensuring seamless operation. The built-in safety and error detection system alerts users to any abnormalities, enhancing reliability and ease of use.

5. How does the Water Vapour Permeability Tester control test conditions such as temperature and humidity?

Water Vapour Permeability Tester features an advanced control system that maintains stable testing conditions. It supports a temperature range of 5°C to 55°C with a fluctuation of ±0.05°C and a humidity range of 5% to 90%. A 360° air circulation system ensures uniform conditions, while real-time monitoring allows for accurate and repeatable test results.
