Conductivity-meters

Optimal measurement of conductivity

In water treatment for medical and industrial equipment and plant construction, different requirements are placed on conductivity measurement.

Conductivity meters perform important measurement and control functions in water treatment.

Salts, acids, and alkalis in aqueous solutions can be detected by a measurement value in μS/cm. These measurement ranges start at 0.05 μS/cm for pure water and go up to acids and alkalis with 1000 mS/cm.

Since temperature fluctuations of the aqueous liquid to be measured have a significant impact on the measurement value, high-quality conductivity meters have built-in temperature compensation. An NTC or PT resistor integrated into the measuring cell electronically corrects the measurement value.

In addition to capturing conductivity values, certain conductivity meters have switching and control contacts. These can switch directly or with a delay and control downstream pumps, valves, etc. Special devices additionally monitor water pressure, water shortage, and, through level control, the fill levels of water tanks and basins.
