Continuous In-line O₂ Measurement in Liquids and Gases
 
OXYTRANS TR Eco is the in-line economy version for 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 LED light. Oxygen transfers energy from the excited molecules and reduces the detected signal. Other gases do not affect the measurement result.
 
Applications
 
 
 
Deaerated Water
 
 
Wort
 
 
Beer
 
 
Beverages
 
 
Liquid Food Products
 
 
CO₂
 
 
Inert Gases
