C406H Oxygen/Water Vapor Transmission Rate Test System
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 D3985、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.

  • Films
    The oxygen and water vapor transmission rate tests of various plastic films, paper-plastic composite films, co-extrusion films, aluminized films, aluminum foil composite films, glass fiber aluminum foil paper composite films and other film-like materials.
  • Sheet
    The oxygen and water vapor transmission rate tests of PP sheet, PVC sheet, PVDC sheet, metal foil, rubber sheet, silicon sheet and other sheet materials.

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's 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.
  • In the test process, the automatic control of flow, temperature, and relative humidity are realized, reaching higher accuracy.
  • The test cell is equipped with a high-precision humidity sensor to monitor and record humidity changes in real-time.
