BOILER DISSOLVED OXYGEN CONTROL
and that the dissolved oxygen is monitored on a regular basis to see the performance of the deaerator. The deaerator is designed to operate for extended periods with no attention other than adjustments to the steam flow. With continuous on-line ppb DO measurement the operators can optimize steam flow for

TOTAL DISSOLVED SOLIDS MEASUREMENT - IC Controls
iccontrols.comTotal Dissolved Solids Definition: Total Dissolved Solids (TDS) is a measure of the sum of all inorganic and organic substances in a liquid in molecular, ionized or micro-granular colloidal suspended form. The solids must be small enough to survive filtration through a sieve the size of two micrometer. TDS solids are normally found in all ...
High Purity Water Resistivity/ Conductivity Measurement
iccontrols.comHigh Purity Water Resistivity/ Conductivity Measurement 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.
