Reliant Water 10254 Galvanic DO Sensor with 30' Cable and Tinned Leads

The Model 20 DO sensor utilizes proven galvanic sensing technology - without a question the most accurate and reliable DO sensing technology ever developed. The pure platinum cathode makes the sensor incapable of being poisoned by other gases often found in impure waters, such as hydrogen sulfide. This sensor utilizes the only DO sensing technology that is successful in continuous de-nitrification monitoring and control applications. It is also the only sensor design that can be used continuously in very violent pure liquid oxygen injection systems. Complete systems are supplied with over 5 years of sensor electrolyte and membranes. When used correctly these Teflon membranes will last well over a year and can be made to require a minimum of maintenance.
