Plastic film analyzer W201 2.0

for the food industryfor pharmaceutical productsfor electronics

Product Introduction
This instrument is developed and manufactured according to the electrolytic test principle in line with GB/T 21529, ISO 15106-3 and related standards. It measures moisture vapor transmission rate (WVTR) of samples under controlled temperature and humidity. Suitable for WVTR testing of high-barrier films and sheets used in LCD displays, solar cells, chip packaging, pharmaceuticals, food and other industrial applications.

Test Principle
The W201 2.0 adopts the electrolytic method. The prepared sample is mounted centrally in the test chamber, creating high-humidity and low-humidity compartments. Humidified nitrogen flows on the wet side while dry nitrogen (carrier gas) flows on the dry side at a set rate. Driven by the humidity gradient, water vapor permeates through the sample and is carried by the dry nitrogen to an electrolytic sensor. The sensor output is processed to determine WVTR and related parameters.
