BOILER DISSOLVED OXYGEN CONTROL
feedwater or closed heating/cooling systems to be kept below 5-10 µg/L (5-10 ppb). Achieving this low level of oxygen may require a combination of mechanical and chemical methods in steam and water systems such as the boiler system illustrated in Fig. 3. Other systems, such as a closed hot water heating or

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.
