Controlling TDS in the Boiler Water | Spirax Sarco
An increase in temperature results in an increase in electrical conductivity. For boiler water, the conductivity increases at the rate of approximately 2% (of the value at 25°C) for every 1°C increase in temperature. This can be written as: Example 3.12.3. A boiler water sample has an unneutralised conductivity of 5 000 μS/cm at 25°C.
