Evaluating the risk of corrosion
The following formula can be used for evaluation:
Calculated conductivity = measured conductivity [μS/cm] – (measured total hardness [dH GH] x constant)
– Measured conductivity in μS/cm
– Measured total hardness in dH GH
– Constant = 30 [μS/cm]/[ dH GH]
Calculated conductivity Risk of corrosion
<200μS/cm low
200 – 500μS/cm increased
>500μS/cm high
Calculation example:
– Measured conductivity 700 μS/cm
– Measured total hardness 18 dH GH
– Calculated conductivity = 700 μS/cm – (18 x 30 μS/cm) = 160 μS/cm
The result of the calculation is 160 μS/cm and means that there is a low risk of corrosion.
