SN-W01E WVTR Tester

The water vapor barrier tester is a precision instrument designed to measure the water vapor transmission rate (WVTR) of materials, based on the test principle of infrared method, evaluating their ability to block or allow moisture transfer. This water vapor permeation analyzer is critical for industries requiring strict control over moisture-sensitive products, such as food packaging, pharmaceuticals, electronics, and textiles.

Product Introduction

Standards

ASTM E96, GB/T 1037, GB/T 16928, ASTM D1653, ISO 2528, TAPPIT464, DIN 53122-1, YBB00092003-2015

Application Fields

Intended Use

Suitable for water vapor transmission rate (WVTR) testing of packaging materials such as plastic films, composite films, sheets, plastic bottles, and plastic bags.

Operating Principle

Distilled water is placed in the test cup, and the pre-conditioned specimen is clamped onto the cup, which is then placed in the test chamber. Water vapor permeates through the specimen into the dry side. By measuring the change in the overall weight of the test cup over time, the water vapor transmission rate (WVTR) of the specimen is calculated.
