WPT_301 Water Vapor Transmission Rate Tester

WPT_301 Water Vapor Transmission Rate Tester

WPT_301 Water Vapor Transmission Rate Tester is for the water vapor transmission rate measurement of plastic films, laminated films, sheets as well as various materials used in medical and construction industries. Through water vapor transmission rate testing, the demands for control and adjust technical indexes and satisfy

Principle

A specific humidity difference is formed among the two sides of the specimen under a certain temperature. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the cup, water vapor transmission rateand other parameters can be obtained.

Characteristics

• Weighing method test principle, intermittent weighing that meets the requirements of the standard, the system is automatically cleared before each measurement to ensure the unity and accuracy of the data
• High-definition LCD touch screen, the content is more intuitive and the operation is easier
• One sample is tested in a single test, the process is fully automated, the lifting and weighing of the breathable cup is controlled by a cylinder, and the data is accurate and reliable
• Innovative circulating dehumidification system, built-in vacuum pump, effectively preventing the formation of humidity gradient above the moisture permeable cup, ensuring the accuracy of the test
• Wide range, high precision, automatic temperature and humidity control, to meet the test under various test conditions
• Test results support multi-format storage and data output, including test report Excel, cloud sharing
• Provide fast calibration mode of standard weights, weighing system to ensure the accuracy of test data
• The product complies with GMP user level three authority
• Perform single and group statistical analysis of test results
• With ISP online control and upgrade functions, the test function can be changed remotely as required
• Special computer communication software, real-time display of test, data analysis and processing, data storage
