OTR-O3 Oxygen Transmission Rate Tester (Coulometric sensor method) OTR-O3 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. This instrument can be used to measure the oxygen transmission rate of barrier materials with high and medium barrier properties with high accuracy and high efficiency. The instrument has a patented integrated three 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-O3 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  The three permeation cells are completely independent, and can test three identical specimens or distinct specimens simultaneously  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 Tel：+86-531-88983898,88983889
