OXYTRANS EC is an electrochemical Clark-cell sensor for high-precision measurement of dissolved and gaseous oxygen (O₂). Depending on its configuration, the sensor covers very low trace levels through to high concentrations and is suitable for beverage, pharmaceutical, power and steam, and semiconductor / ultrapure-water applications.
 
Applications
 
 
 
Beer and beverage production
 
 
Power & Steam
 
 
Pharmaceuticals & Chemicals
 
 
Semiconductor / Ultrapure Water
 
 
Measuring Principle
 
O₂ diffuses through a semi-permeable membrane to the cathode of the Clark cell. The electrochemically generated current is proportional to the oxygen partial pressure. Sensor parameters can be stored in the sensor, simplifying changes between compatible evaluation units.
