Potentiostatic D.O. sensor with integrated temperature sensor


Design according to the minimum requirements for measuring instruments used at
waste water treatment plants defined by ATV (waste water association) in bulletin M256.

Potentiostatic D.O. sensor (3-electrode principle)
to be connected to the EcoLine or QuadroLine series measuring transmitters;
especially suitable for use in denitrification and for oxygen addition measurements.
