C230H Oxygen Transmission Rate Test System
The C230H Oxygen Transmission Rate (OTR) Test System is engineered using the advanced coulometric sensor method (also known as the equal pressure method) and fully complies with ASTM D3985 standards. It is designed to deliver highly accurate and efficient measurement of oxygen transmission rates in materials with medium to high barrier properties.
Featuring Labthink’s patented integrated test block design, the system includes three permeation cells to support efficient and reliable testing. At its core, a high-precision coulometric sensor works in conjunction with Labthink’s advanced computer-controlled system to ensure exceptional performance.
The instrument provides precise control over temperature, humidity, and gas flow rate, enabling consistent test conditions and delivering high sensitivity with outstanding repeatability.
Ideal for quality control and research applications, the C230H offers a dependable solution for evaluating oxygen permeability in barrier materials, helping manufacturers maintain product integrity and meet industry standards.
