Test Principle
The pre-conditioned specimen is clamped in the test cell, nitrogen with stable relative humidity flows on one side of the specimen while a stream of dry nitrogen flows on the other side. Due to the humidity difference, water vapor permeates through the specimen from the high humidity side into the low humidity side, and is carried to the infrared sensor by the dry nitrogen flow. By analyzing the electrical signals generated by the water vapor, the sensor calculates the water vapor concentration and the water vapor transmission rate.

FAQ's of Water Vapor Transmission Rate (WVTR) Testing for Aluminium Papaer Packaging:
Q: How is water vapor transmission rate measured for aluminium paper packaging using this tester?
A: The WVTR Tester determines the moisture barrier performance of aluminium paper packaging by measuring the rate at which water vapor passes through a packaging material under controlled temperature and humidity, following ASTM E96 and ISO 2528 standards. The integrated infrared/coulometric sensor quantifies the vapor, and the process is managed through a microcomputer for precise control and automatic operation.
Q: What are the preparation steps and process for running a WVTR test?
A: To perform a test, specimens of 80 mm size are placed in the stainless steel chamber. Conditions for temperature (15C-50C) and humidity (10%-90% RH) are set via the control panel. The test is initiated from the digital interface, with adjustable test speed and stroke. Data is captured by the sensor and can be logged or printed for records.
Q: When should the WVTR tester be calibrated?
A: The WVTR tester comes factory calibrated to international standards. Nonetheless, periodic user calibration is recommended to maintain high accuracy (0.01 g/m224h). The calibration frequency often depends on usage intensity and laboratory protocols but is generally advisable before major testing campaigns or after extended periods of inactivity.
Q: Where can this WVTR tester be effectively utilized?
A: This equipment is designed for laboratory and industrial environments, accommodating needs in quality control, research, and manufacturing settings.
