Oxygen3

Polarographic Dissolved oxygen sensor

The S423 solves this problem by using an OPTIFLOW™ membrane. This
membrane is very mechanically stable, is manufactured as a laminate
around a steel mesh and is very resistant to chemically aggressive
environments as well as high pressures.
Thanks to the special construction of the measuring electrodes, this system
also makes the sensor totally “maintenance free”.
