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.

Product Introduction The headspace gas analyzer adopts the destructive puncture detection method and is equipped with high-precision oxygen sensors and carbon dioxide sensors to accurately detect the O2 and CO2 content of hollow packaging containers such as packaging bags, bottles, cans, etc. The analysis of the content of the headspace gas in the packaging can make a reasonable judgment on the product quality, the validity of the shelf life prediction, and the rationality of the packaging design. At the same time, it can also be used as a means of packaging tightness testing. It is a better choice for modified atmosphere preservation (MAP, CAP) packaging, large infusion bottles (bags), residual oxygen in the headspace of prefilled needles, residual oxygen detection in vials, and the results of residual oxygen detection for various food and medicines. Nowadays, the headspace gas analyzer has become an important method to check the quality of packaging design and one of the important methods to verify the product shelf life. Our headspace gas analyzer GB-DK can quickly detect O2 in production lines, warehouses, laboratories and other occasions. And CO2 content to guide production.   Test principle The gas in the sample is drawn into the sensor by a vacuum pump. The sensor outputs the current and voltage signals of the O2 and CO2 (optional) concentration in the gas in the sample in real time. The instrument calculates the content of O2 and CO2 in the gas by obtaining the current and voltage signals output by the sensor. After reaching the end conditions of the experiment, the test stops, and the instrument records the concentration of O2 and CO2 in the measured gas in the sample.   Technical parameter Item Parameter Gas to be Measured O2 (standard configuration) CO2 (optional) Measurement Principle Fluorescence optics infrared absorption Measurement Range 0%～25% (for O2) 0%~100% (for CO2) Measurement Accuracy ±0.2% ±2% Sample Size ≥5 mL (at standard atmospheric pressure) (for O2) ≥20 mL (at standard atmospheric pressure) (for CO2) Dimensions 350 mm (L)×330 mm(W)×200 mm(H) Power Supply 220 VAC±10 % 50Hz/120 VAC±10 % 60 Hz Net Weight 5kg    Features 1.Using high-precision sensors, high accuracy, good stability, long-term operation, long service life.
