OX2/230 Oxygen Transmission Rate Test System


Professional, High Efficiency and Intelligent OTR Test System



This instrument can be used to measure oxygen transmission rate of film and package specimens. It has three test modes and is applicable to various materials with high, medium and low oxygen permeability. It is also embedded with high precision oxygen sensor, which provides a wide test range of 0.01~65000cm3/m2·d and durable service life.

  • Wide range and high precision of temperature and humidity control, adding humidity to two sides of the specimen, to support various combinations of non-standard test conditions
  • World leading pressure compensation technology ensures accurate and repeatable test results
  • Standard, proportional and continuous testing modes facilitate to minimize errors caused by human factors during test process
  • Equipped with catalyst deaerator to purify carrier gas and reduce system errors
  • 2 types of carrier gases are available: High purity nitrogen gas or hydrogen-mixed nitrogen gas
  • Convenient fast-access calibration port for temperature and humidity
  • Reference film for accurate calibration


High Efficiency

OX2/230 system is based on the equal pressure method and adopts Labthink’s latest exclusive patent design of three diffusion cells integrated in one instrument for individual or multiple tests, which improves test efficiency by 3 times. It can be easily connected with 9 satellite bases together to accomplish up to 30 tests at the same time.

  • 3 diffusion cells are integrated in one instrument with lower space occupancy rate and higher test efficiency
  • 3 distinct or equivalent specimens can be tested individually with independent test results at one operation
  • The system can be easily connected with a maximum of 10 instruments to accomplish up to 30 tests at the same time
  • Oxygen transmission rate and water vapor transmission rate can be obtained at one operation by working with Labthink’s water vapor transmission rate test system together under the control of one computer
  • Intelligent


The instrument utilizes Labthink’s latest operating software with user-friendly operating interface and intelligent data management. It also supports LystemTM Lab Data Sharing System, which ensures uniform management of test results and test reports.

  • Based on the user-friendly Windows operating interface for easy operation
  • Saves test data in different formats for convenient data transfer
  • Intelligent historical data searching, comparison, analysis and printing functions
  • Supports LystemTM Lab Data Sharing System for uniform management of test results and test reports
