CDE 2: Potable water and water of similar quality, surfactant-free.
CDE 3: as CDE 2 but up to 60 °C.
CDE 2-mA-0.5 ppm: 0.01 ... 0.5 mg/l, standard slope: 24 mA/ppm.
CDE 2-mA-2 ppm: 0.02 ... 2 mg/l, standard slope: 6 mA/ppm.
CDE 2-mA-10 ppm: 0.1 ... 10 mg/l, standard slope: 1.2 mA/ppm.

Ø 1 year, depending on the water quality.
The presence of agents decreasing the surface tension (surfactants)
can significantly reduce the service life. ProMinent offers a surfactant-
proof sensor type CDP 1-mA-2 ppm.
