Portable O₂ Measurement in Liquids and Gases
 
OXYTRANS M Eco is the portable 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
