Today’s process world is a challenging one. Plant managers, metrology labs, and maintenance workers are constantly asked to improve their process efficiencies and output while at the same time seeing their budgets, manpower, and workforce reduced. Fortunately, companies that serve the process industry have used these imposed limitations as an impetus to improve [...]
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 [...]
Case Study – High purity Thermo Scientific Orion ROSS pH electrode provides reliable measurements and cost savings in steam cycle monitoring and control applications The Right pH Electrode for Steam Cycle Monitoring and Control A steam generating plant requires very clean water and carefully controlled chemistry for proper operation of a boiler that runs [...]
Ultra-Pure Water without any chemical impurities will still have a conductivity because of the presence of H+ and OH- ions due to the self-ionization of water. Ultra-pure water has a conductivity of 0.055 μSiemens/cm or a resistivity of 18.18 mΩ·cm at 25°C. In order to know the conductivity or resistivity of ultra-pure water [...]
