Graduated measuring ranges 0.01 µS/cm – 2,000 mS/cm. Conductivity sensors for optimum process integration: DULCOTEST sensors meet a wide range of measuring requirements and allow the best solution to any given measuring task to be achieved.
Online measurement of electrolytic conductivity – with the reliable DULCOTEST sensors.
After pH, electrolytic conductivity is the second most important measured variable in chemical process analysis. It characterises the ability of an aqueous solution to conduct electrical current. This allows all processes involving salts, acids and bases to be accurately monitored and controlled.
The field of application covers everything from fairly simple water treatment tasks through to complex industrial process waters with stringent requirements in terms of temperature, pressure, contamination tolerance and chemical resistance (e.g. to concentrated sulphuric acid or hydrofluoric acid).

2-Electrode Conductivity Sensors
Conductive conductivity sensors measure the electrolytic conductivity indirectly via the charge transfer between two electrodes immersed in the medium to be measured. The sensor types with cell constants k = 0.01 and k = 0.1 cm-1 are especially suitable for the measurement of the lowest electrolytic conductivities of < 1 µS/cm in pure and ultra-pure kinds of water.
The sensor types with cell constants k=1 cm-1 are used in numerous kinds of water without film-forming ingredients up to 20 mS/cm. The cost-effective sensor range LF(T) is used in clear, chemically uncontaminated water.
The sensor ranges LM(P), CK and CKPt can also be used in chemically contaminated kinds of water and a high temperatures.
