Pubtester ASTM D3985 Coulometric Sensor Method OTR Oxygen Permeability Tester China Manufacturer

Product Description

OTR-O3 Coulometric Sensor Method OTR Oxygen Permeability Tester
(Coulometric sensor method)
OTR-O3 Coulometric Sensor Method OTR Oxygen Permeability 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 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 Efficient and Intelligent Whole process monitoring, automatic recording, adjustable sampling rate, test process can be reproduced throughout The software functions are professional and intuitive, personnel permissions are strictly graded, and report output forms are diverse Intelligent air-saving function can reduce the consumption of test gas Optional accessories extend the capability to testing containers The system is controlled by a microcomputer, equipped with a tablet and a menu-type interface, which is convenient for users to quickly and intuitively view the test data and results Equipped with RS232 data interface and computer software to facilitate data transfer The software complies with the requirements of China's "Good Manufacturing Practice for Pharmaceutical Products" (GMP) Test PrincipleThe pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. The upper chamber contains oxygen or air and the lower chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side and are taken to the coulometric sensor where proportional electrical signals are generated. The oxygen transmission rate is then obtained by analyzing the signals and calculating the volume of oxygen measured by the sensor.
