How can the concentration of NaOH, in water solution, be measured while the solution is in a vacuum evaporator? The goal is to take the concentration to say 28% to cause the precipitation of a crystalline material.
My list of potentials include pH, Conductivity, Density and Viscosity.

I am investigating a process that includes concentrating 5,000 gallons of a 25% NaOH, 75% water mixture to 40% NaOH, 60% water mixture. I will have 24 hours to process a batch. It will have to be done with no operator in attendance. The system will be monitored as needed remotely...
