WPT_304 Water Vapor Permeability Tester

WPT_304 Water Vapor Permeability Tester based on the gravimetric method is applicable to test the water vapor transmission rate of plastic film, composite film, sheet, and other materials used in packaging, medical and construction industry.

Features

Standard periodic weighing method and auto-zeroing function guarantee the accuracy and uniformity of the testing data.
Touch interface is more convenient to operate.
4 specimens can be processed independently with individual result in one test automatically.
Electrical cylinder lifting structure and automatic weighing calibration mode ensure the accuracy of data.
Innovative circulating dehumidification system can effectively prevent the formation of humidity gradient and ensure accuracy.
Automatic control system of temperature and humidity can be used under different conditions.
Adjustable air velocity enables the appropriate humidity for testing.
The data can be stored and outputted in multi-format (including reports in excel and cloud sharing).
GMP management of user's three-level authority complies with international standards.
The instrument processes statistical analysis of single and group data.
Equipped with ISP control online and upgrade function.
Specialized communicating software can display in real-time, analyze and store data.
