Accurate pH measurement in very low conductivity water requires a highly specialized sensor
To ensure that chemical treatment is working effectively, pH measurement after the demineralizer is important. However, as the water has negligible electrolytic conductivity at this stage, pH measurement is very difficult.
Achieving the required measurement accuracy from pH sensors used to be a complicated, maintenance-intensive operation. METTLER TOLEDO Thornton has solved this measurement challenge with the pHure Sensor LE.
