The In-Situ® Clark cell dissolved oxygen (DO) sensor is a polarographic sensor that contains replaceable membrane and filling solution. Clark cell sensors measure DO indirectly through an electrochemical reaction.
In-Situ offers 1-mil and 2-mil Teflon® membranes to suit your application requirements.
As an alternative to the Clark cell sensor, use the technologically advanced RDO® optical DO sensor.
Use the Clark cell DO sensor with the TROLL® 9500 water quality instrument. The following TROLL 9500 configurations are available:
TROLL 9500 sub-2" instrument outfitted with Clark cell sensor, turbidity/pressure sensor, conductivity, pH/ORP sensors, and one ISE sensor
TROLL 9500 sub-2" low-flow sampling system
