C230h Oxygen Transmission Rate Test System

Product Features

New Generation Integrated Testing Block
The patented three-cell integrated test block structure using advanced thermodynamics and hydrodynamics analysis greatly improves the temperature, humidity and flow measurement accuracy across the three test cells and supports simultaneous testing of three samples.

Automatic Control of Temperature, Humidity and Flow Rate
The internal temperature and humidity of the instrument are automatically adjusted with temperature and humidity sensors, maintaining the stability of the test specimen environment.
Automatic flow rate control ensures the constant flow during the testing process and minimizes any errors caused by an unstable flow rate.

Easy-to-use and High-efficiency System
The automatic test mode, combined with the instrument features, eliminates the need for manual adjustments to quickly obtain accurate results, saving training costs and releasing staff from manual monitoring so that they are available for other tasks.
The professional test mode provides flexible and rich instrument control functions to meet individual scientific research needs.
Unique, optional DataShield^TM system, meets the requirements for centralized management of user data. It supports a variety of formats of exported data. Reliable security algorithms are used to prevent data leakage. It supports universal wired and wireless LAN, optional private wireless network and third-party software.

User-oriented Service Concept
Adhering to our user-oriented service concept, Labthink has created a customization system that provides flexible and comprehensive customization services for the accommodation of non-standard specimens and packages.

Note 1: The parameters in the table are measured by professional operator in Labthink laboratory according to relative requirements for laboratory standard conditions.
Note 2: DataShield^TM provides safe and reliable data application support. Multiple Labthink instruments can share one single DataShield^TM system which can be purchase as required.
Note 3: The described product features should be in line with Table 1: Test Parameters.

Test Principle

The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. The upper chamber contains oxygen or air and the lower chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side and are taken to the coulometric sensor where proportional electrical signals are generated. The oxygen transmission rate is then obtained by analyzing the signals and calculating the volume of oxygen measured by the sensor. For whole package samples, high purity nitrogen flows inside the package, and oxygen or air flows outside.
