C406H Oxygen /Water Vapor Transmission Rate Test System C406H Oxygen /Water Vapor Transmission Rate Test System is based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured according to ASTM D3985x ASTM F1249, ISO 15106-2 and other relevant standards to provide high precision and high efficiency oxygen and water vapor transmission rate tests for high and medium gas barrier materials. It is suitable for testing the oxygen and water vapor transmission performance of films, sheets and related materials in the fields of food, medicine, medical devices, daily chemicals, photovoltaic, electronic and many others. OTR/WVTR tested in One Instrument • OTR \ WVTR mode, OTR mode and WVTR mode are available for selection. • OTR and WVTR tests can be automatically completed for each sample mounting. • Genuinely reflect the OTR \ WVTR performance of the same sample, avoiding effect on test data due to sample contamination arising from instrument switching Coulometric Oxygen Sensor • The instrument is equipped with a ppb level Coulometric Oxygen Sensor, as one of new Labthink technical achievements, which can obtain a lower limit of the test. • Designed according to ASTM D3985 with absolute value, and no calibration is permitted. • Longer service life, two times longer than that of a traditional Coulometric oxygen sensor. • Over limit alarm and automatic protection. Infrared Moisture Sensor • The instrument is equipped with Labthink patented infrared moisture sensor which can obtain a lower limit of the test. • Designed according to ASTM F1249. • Longer service life, non-consumable. • Over limit alarm and automatic protection. Accurate Data • Brand new rainbow bridge structural test cell and 360° air circulation constant temperature technology ensure better temperature stability. • The test cell is equipped with a high-precision humidity sensor to monitor and record humidity changes in real time.

• In the test process, the automatic control on flow, temperature and relative humidity is realized, reaching higher accuracy. High Efficiency 6 Test Cells • Independent six sets of 50cm2 standard area test cells, which is three times the traditional oxygen transmission rate test instrument. • Six samples can be tested at the same time under the same condition, with independent tests data. • In the same test cycle, the number of samples completed increases from 2 to 6. • Automatic sample clamping, saving time and effort, ensuring consistent clamping force and better sealing. Intelligent Operation...

The pre-treated sample is clamped between the test chambers, oxygen or nitrogen with stable relative humidity flows on one side of the film, and the high purity nitrogen flows on the other side; oxygen or water molecules diffuse through the film into high-purity nitrogen on the other side, and are carried to the sensor by the flowing nitrogen. By analyzing the oxygen or water vapor concentration measured by the sensor, the oxygen or water vapor transmission rate can be calculated.
