max. depth 2,000m
The Clark electrode measures dissolved oxygen with a membrane-covered galvanic cell. The sensor is designed for long-term measurements in ponds, lakes and oceans at depths up to 2,000 m.
The sensor comes with pressure and temperature compensation and is insensitive to hydrogen sulphide.
The sensor has a limited lifetime of typical 12 – 16 months, then the membrane requires replacement.
