FAQs

1. What industries commonly use this Water Vapour Permeability Tester?

Water Vapour Permeability Tester is widely used in industries where moisture control is essential. It is commonly employed in the packaging industry to evaluate the barrier properties of films and containers used for food, medicine, and electronic products. The food industry utilizes it to ensure that packaging materials provide adequate moisture protection to extend product shelf life. Pharmaceutical companies use it to test blister packs, vials, and other medical packaging to prevent moisture-related degradation. Additionally, it is used in research and material development to assess the moisture resistance of new materials.

2. How many samples can be tested at once?

This Water Vapour Permeability Tester features a three-chamber design, which allows up to three samples to be tested simultaneously. Each chamber operates independently, meaning different materials can be tested under separate conditions within the same test cycle. This multi-sample capability improves efficiency and enables comparative analysis of different materials in a single test run. If needed, the chambers can also be used separately for individual tests, giving users greater flexibility in their experiments.

3. Does the Water Vapour Permeability Tester require a computer for operation?

Water Vapour Permeability Tester does not necessarily require a computer for operation. It is equipped with a built-in touchscreen interface that allows users to control settings, monitor real-time data, and analyze results directly on the device. However, for enhanced functionality, such as data storage, report generation, and advanced analysis, the instrument can be connected to a computer via the RS232 port. This enables seamless data transfer and integration with laboratory management systems.

4. How is humidity controlled in the testing process?

. Water Vapour Permeability Tester features an advanced automatic humidity control system that ensures precise and stable humidity conditions during testing. It uses a reference air flow method to regulate humidity levels, preventing external environmental fluctuations from affecting test results. The dehumidification system helps maintain consistent conditions, ensuring the accuracy and repeatability of moisture permeability measurements. This is particularly important when testing materials that are highly sensitive to humidity changes.

5. Can test results be saved or printed?

Yes, the Water Vapour Permeability Tester allows users to save and print test results for documentation and analysis. The instrument supports data storage in multiple formats, including and , which can be accessed and transferred to external devices. It can also be directly connected to a printer for on-demand report generation. Additionally, the system provides real-time graphical display and data tracking, making it easier to monitor trends and analyze material behavior over time.
