Oxygen transmission rate tester C203H

permeabilityfor packagingfor composites

203H Oxygen Transmission Rate Test System is based on Coulometric oxygen analysis sensor and equal pressure test metod, and is conforming to ASTM D 3985 and other standards. It provides high-precision and high-efficiency oxygen permeability tests for high and medium gas barrier materials. It is suitable for testing the oxygen permeability of thin films, sheets and related materials in the fields of food, medicine, medical devices, daily chemical, photovoltaic, electronic and other fields. Product Features Coulometric Oxygen Sensor The instrument is equipped with ppb level Coulometric Oxygen Sensor of Labthink which can obtain lower test limit. Designed according to ASTM D3985 with absolute value and no need to calibrate. Super long service life, three times longer than traditional Coulometric oxygen sensor. Functions of over limit alarm and automatic protection. Accurate Data Using 360 ° air circulation constant temperature technology, the temperature stability is better. Equipped with high-precision temperature and humidity sensor, real-time monitoring and recording temperature and humidity changes. In the test process, the automatic control of flow, temperature and relative humidity is realized, and the accuracy is higher. Higher test repeatability of 0.02 cc / (m2·day) can be achieved. Effective Three-Cell Independent three sets of 50cm2 standard test area cells, in line with the standard requirements for parallel sample detection. Three samples are tested at the same time under the same condition, and the data are independent. Standards ASTM D3985, ASTM F1307, GB/T 19789, GB/T 31354, DIN 53380-3, JIS K7126-2-B, YBB 00082003-2015
