User-oriented Service Concept
Adhering to our user-oriented service concept, Labthink has created a customization system that provides flexible and comprehensive customization services for the accommodation of non-standard specimens and packages.
Test Principle
The test specimen is mounted in the test dish which contains water or desiccant inside. The test dish is placed in the test chamber with stable temperature, humidity and air flow. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the test dish periodically, water vapor transmission rate and other parameters can be obtained.

FAQ's of Water Vapor Permeation (WVP) Measurement of Plastic Composite (APC) Film:
Q: How does the WVP Tester measure water vapor permeation in APC films?
A: The Water Vapor Permeation Tester utilizes the gravimetric (weight change) method, where the change in specimen weight over time reflects the amount of water vapor transmitted through the film. The fully automatic calibration system, using a reference membrane, ensures reliable and reproducible results.
Q: What types and sizes of specimens can be tested with this equipment?
A: The tester is designed for plastic composite (APC) films, sheets, and flexible packaging materials. It accommodates 1-3 specimens simultaneously, with each specimen size up to a diameter of 80 mm and a maximum test width of 100 mm.
Q: When should calibration be performed, and how is it managed?
A: Calibration is automatically managed by the device using a built-in reference membrane. This process ensures measurement accuracy and does not require manual intervention, streamlining preparation between batches and tests.
Q: Where can this instrument be installed for optimal workflow?
A: This WVP Tester is intended for bench-top mounting in laboratory and quality control environments, such as research institutes, manufacturing facilities, and packaging material analysis labs. Its compact footprint and durable powder-coated steel enclosure make integration simple and secure.
Q: What is the process for conducting a test with this device?
A: After placing the specimens in the designated chambers, the operator selects test parameters via the LCD digital interface. The microcomputer control system regulates temperature and humidity automatically, initiates testing, and logs up to 100 results for further analysis.
Q: How does the device support reliability and safety during operation?
A: An automatic over-limit alarm system is built in to notify operators immediately if test parameters exceed set thresholds, protecting specimens and equipment. Additionally, automatic temperature and humidity adjustments optimize testing conditions for each run.
Q: What are the primary benefits of using this WVP Tester for APC film analysis?
A: Benefits include highly accurate and repeatable water vapor transmission measurement, multi-lingual operation, compliance with international standards, large storage capacity, and a robust design suitable for routine laboratory use.
