C203H 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 FeaturesNote1
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.
- In the same test cycle, the number of samples completed increases from 2 to 3.
- Automatic clamping sample, saving time and labor, clamping force is consistent, better sealing.
Intelligent Operation
- The 12 Inch Touch panel of windows system is used for more convenient operation.
- Automatic mode - after inputting the test temperature and humidity and clicking one key to start the test, the test proceeds automatically.
- New drawer type test cell, one key automatic in-and-out with sound and light reminder.
Safe and Reliable
- Safe Running: the innovative Labthink’s high-end industrial computer is embedded to eliminate the system failure caused by computer virus, and ensure the operation reliability and data storage security.
- Safe Operation: equipped with optical and other intelligent sensors as well as sound and light intelligent alarms to ensure the safety of operation.
- Safe Performance: the instrument uses global famous brand with stable and reliable performance.
Powerful Functions
- Professional test mode provides flexible and rich control functions to meet the needs of scientific research.
- Provide oxygen permeability curve, oxygen transmission coefficient curve, temperature curve and humidity curve.
- Ultra wide test range, meet the barrier test (customized) of various materials.
- Ultra wide temperature range, meet the barrier test at different temperatures (customized).
- The gas purification device independently developed by Labthink can remove trace oxygen in nitrogen and provide oxygen free carrier gas (optional).
Testing Principle
The sample is clamped between the test chambers, oxygen or air flows on one side of the film, and high-purity nitrogen flows on the other side of the film. Oxygen molecules diffuse through the film into the high-purity nitrogen in the other side. The flowing nitrogen is carried to the sensor. Through the analysis of the oxygen concentration measured by the sensor, the oxygen transmittance is calculated.
