Working principle

W303 Water Vapor Permeation Tester was designed with the principle of weighting method to use weight reduction method to test the water transmittance rate (WVTR) of plastic films. Namely in the regulated temperature, relative humidity conditions, the sample two sides keep the vapor different pressure, measuring the vapor volume passed through, figure out the WVTR value. Unit is g/ m²·24h.

Techinical Parameter

Features:

Precise & Reliable 

• High precision sensor, continuous data collecting, accurate and dependable. 
• Test accuracy reaches 0.001 g / (m2·24h), which stays in leading position of the industry. 
• 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. 
• The discreteness of data for the same sample is less than 5%.
