Application
To test the water vapor transmission rate (WVTR) of packaging materials, such as plastic film, composite film, coextrusion film, aluminum-plated film, aluminum foil, infusion bag, sheets, paper, paper board, solar battery panel, cellophane, ceramics and porcelain, and various containers such as bag, pouch, bottle, can, bowl, and box. It is widely used in the industries of food, pharmaceuticals, personal care, household, electronics and so on and institutions of quality control, drug inspection and science research.
Working principle
Weight reduction method (wet cup method). Fill the test dish with distilled water (according to stipulation of ASTM E 96), seal the cup with test sample, keep humidity difference between inside and outside of the cup, and water vapor will penetrate the test sample; monitor the change of cup weight to calculate transmission rate.
Standards
GB/T 1037、GB/T 16928、YBB00092003、ASTM E96、ASTM D1653、ISO 2528、TAPPI T464、DIN 53122-1、JIS Z0208
Features
Ø Precise & Reliable
l High precision sensor, continuous data collecting, accurate and dependable.
l Test accuracy reaches 0.001 g / (m2·24h), which stays in leading position of the industry.
l Adopt the only Standard Films in the industry which are authorized by AQSIQ and developed by GBPI to verify the instrument, and the data are 100% reliable.
l The discreteness of data for the same sample is less than 5%.
Ø Multi-testing Chambers to test samples flexibly and Efficiently
l Three chambers with unique sensor in every chamber. Can stop any one of the chambers to change sample, which can effectively enhance the test efficiency.
l Three chambers can test three different samples at the same time.
l Can extend to the maximum of six chambers. Every chamber works independently.
