O₂ Measurement in Liquids
 
OXYTRANS TR-K is an optical oxygen sensor for O₂ measurement in deaerated water, wort, beer, beverages and liquid food products. The instrument is designed for applications requiring maximum sensitivity and highest accuracy.
 
Measuring Principle
 
Indicator molecules in the optical window are excited by blue-green light. Oxygen transfers the excitation energy and changes the detected signal. Other gases do not affect the measurement result.
 
Applications
 
 
 
Deaerated Water
