Our Process Optical Dissolved Oxygen Electrode enables optical dissolved oxygen measurement technology on existing 4-20mA or 0 to 5VDC test systems. You can now buy just the electrode and not have to invest in a whole new analysis system.

This technology is based on the proven method whereas oxygen concentration is determined by the luminescent quenching of a dye embedded on the sensor surface. Unlike polarographic or galvanic sensors, this optical sensor does not require filling solutions nor a “warm-up” time.

Features:

* Affordable, complete electrode system
* 4-20mA output for existing controllers/monitors
* No electrolyte solution to replenish
* Replaceable membranes
* No calibration or replacement membranes for at least 1 year in most applications
* Saltwater compensation with toggle switch
* Sample flow
