Online detection of caustic soda concentration
Thread Content
May I ask what instruments are used for online monitoring of caustic soda concentration?
One is a densitometer, another is an inductive conductivity meter, and then there is a refractometer
The inductive conductivity meter has a concentration conversion function. Provided that your liquid is an alkaline solution with no other impurities
Conductivity, pH electrodes, densitometers, concentration meters, mass flow meters – all of them work!
