for packagingfor filmfor paper

OTR-O1 Oxygen Transmission Rate Tester (Coulometric sensor method) OTR-O1 Oxygen Transmission Rate Tester, also called oxygen permeability Tester is designed and manufactured based on the coulometric sensor method (as known as equal pressure method) and conforms to ASTM D3985. The instrument has a patented integrated single test permeation cells, high-precision sensors, and built-in dedicated computer control system, providing accurate temperature, humidity, flow rate adjustment and control, with high test sensitivity and excellent repeatability of test results. OTR-O1 is applicable to the determination of oxygen permeability of plastic films, sheeting, paper, and other packaging materials used in food, pharmaceutical, medical apparatus, consumer products, photovoltaic and electronic industries, etc. Technical Features High Precision Advantages Trace oxygen sensor, can measure oxygen content as low as ppb level; pA level micro current measurement, higher measurement accuracy Precise flow control, with professional piping system and flushing technology, effectively ensure the stability and cleanliness of the carrier gas Advanced sample installation anti-leakage technology to effectively ensure the overall sealing of the test chamber Equipped with patented non-fog humidifier, automatic and precise control of high humidity  Semiconductor cold and hot bidirectional temperature control technology, which can increase or decrease temperature at will, with precise temperature control, making the system more stable; Core sensors and other components have multiple self-protection functions Short warm-up time, test conditions can reach the set requirements faster
