Instrumentation and Operational Considerations for On-Line pH Measurement in Samples Below 10 μS/cm Conductivity Ordinarily pH measurements are made in water with 1,000 to 10,000 μS/cm conductivity. The conductivity comes from dissolved solids which are typically salts but also acid or base. These dissolved substances are in the solution in ion form which [...]
