Portable O₂ Measurement in Liquids and Gases
 
OXYTRANS M is the portable version for optical O₂ measurement in liquids and gases. Measured values can be acquired and recorded directly at changing process and inspection points.
 
Measuring Principle
 
Indicator molecules in the optical window are excited by blue-green light. Oxygen changes the detected signal. The portable instrument makes this measurement principle available for portable inspection measurements.
 
Applications
 
 
 
Deaerated Water
 
 
Wort
 
 
Beer
 
 
Beverages
 
 
Liquid Food Products
 
 
CO₂
 
 
Inert Gases
 
 
Inspection Measurement
 
 
Data logging can be manual or automatic. Recording intervals of 5 to 600 seconds, PC software and a USB interface support documentation.
