Conductivity Sensor, Flow-Thru for Mark 18, Mark 20, and Mark 24

Martek sensors are built to the most exacting standards. Each sensor comes complete with its own electronic circuitry secured in a separate NEMA 4X enclosure. This signal conditioning module or preamp permits transmission of interference-free signals over long distances (up to 2,000 feet) and provides electronic calibration for each specific sensor.  All conductivity sensors feature Type 316 Stainless Steel and Teflon materials while pH and dissolved oxygen sensors are manufactured from temperature and corrosion-resistant plastics and precious metals. In addition, all sensors require minimum sample volumes eliminating the need for bulky flow chambers.  For use with the Mark 18, Mark 20, and Mark 24 conductivity preamps.
