OXYTRANS TR – Oxygen (Optical; In-line)
In-line O₂ Measurement in Liquids and Gases
OXYTRANS TR is an optical oxygen sensor for continuous O₂ measurement in deaerated water, wort, beer, beverages, liquid food products, CO₂ and inert gases.
Measuring Principle
Indicator molecules in the optical window are excited by blue-green light. Oxygen transfers the excitation energy and changes the detected signal. As the O₂ concentration increases, the signal decreases.
Applications
- Deaerated Water
- Wort
- Beer
- Beverages
- Liquid Food Products
- CO₂
- Inert Gases
- Product Line
OXYTRANS TR is designed for applications requiring maximum sensitivity and highest accuracy.
