C203H Oxygen Transmission Rate Test System

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.

  • Films
    The oxygen permeability 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 permeability tests of PP sheet, PVC sheet, PVDC sheet, metal foil, rubber sheet, silicon sheet and other sheet materials.

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 360o 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.

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.
