W203 2.0 Water Vapor Transmission Rate Tester Electrolytic Method | High Barrier Materials WVTR Testing Product Introduction W203 2.0 is developed based on the electrolytic test principle, designed and manufactured in accordance with GB/T 21529, ISO 15106-3 and other international standards. It tests water vapor transmission rate of samples under controlled temperature and humidity, widely used for high barrier materials in LCD, solar cells, chip packaging, pharmaceuticals, food and more. Get a Free Quote Today   Test Principle W203 2.0 adopts the electrolytic method. The pre-treated sample is fixed in the test chamber, separating it into wet and dry sides. Humidified nitrogen flows on one side of the film, while dry nitrogen (carrier gas) flows on the other side at a fixed rate. Due to humidity gradient, water vapor permeates from the wet side to the dry side, carried by dry nitrogen to the electrolytic sensor. The WVTR value is calculated from the electrical signal output by the sensor.   Compliant Standards 2025 Chinese Pharmacopoeia 4010 GB/T 21529-2008 ISO 15106-3 DIN 53122-2 YBB 00092003-2015 ASTM F3299 JIS K7129-3   Technical Specifications Item Value Test Range 0.001~40 g/(m²·24h) (Film & Sheet) Resolution 0.0001 g/(m²·24h) Temperature Range 15 ~ 45℃ Temperature Accuracy ±0.1℃ Humidity Range 5 ~ 90%RH Humidity Accuracy ±1%RH Test Area 50.24 cm² Sample Size Φ100 mm Test Chambers 3 channels (independent data)   Key Features High-sensitivity sensor for ultra-high barrier materials in electronics, photovoltaics, displays.

AUTO GBM‑L2 Dual‑Pressure Micro‑Leak Seal Tester: Micro‑Leakage Detection for Pharmaceutical & Food Packaging GBPI AUTO GBM‑L2 Dual‑Pressure Micro‑Leak Seal Tester for Packaging Micro‑Leak Detection Product Introduction AUTO GBM‑L2 Dual‑Pressure Methods Vacuum Decay Leak Detection Tester adopts the test principle of vacuum decay method/pressure decay to detect micro‑leakage of finished packaging. It can be applied to packaging systems composed of vials, ampoules, pre‑filled syringes, eye drop bottles, HDPE bottles, infusion bottles/bags and other pharmaceutical packaging, food packaging, and chemical industry packaging. Testing Principle The host is connected to a sealed test chamber customized according to the sample. When performing the vacuum decay method test, the instrument evacuates the test chamber, and a pressure difference is formed inside and outside the sample. Under the action of the pressure, the gas/liquid in the sample enters the test chamber through the leak hole. The main engine uses the absolute pressure sensor and the differential pressure sensor to monitor the pressure change in the chamber to judge whether the sample leaks. When performing the pressure decay method test, the instrument fills the test chamber with a predetermined air pressure, and the gas in the test chamber enters the sample through the leak hole. The host uses absolute pressure sensors and differential pressure sensors to monitor the pressure changes in the chamber to determine whether the sample is leaking. Executive Standards ASTM F2338‑2009(2013), YY‑T 0681.18‑2020, USP<1207.2>, ASTM F2095, supporting leakage verification for global pharmaceutical and food packaging regulatory requirements.
