Greenspan EC250 Electrical Conductivity Sensor DISCONTINUED

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

Greenspan Electrical Conductivity Sensors use state of the art toroidal measuring system. Microprocessor technology provides accurate temperature compensated measurements. Greenspan EC Sensor combines robust, sealed construction with an electrode-less sensing system to offer unparalleled reliability. Designed for low power consumption, the Sensor can be operated from remote power sources for extended periods. Field experience has shown that the Greenspan EC Sensor can be left unattended for up to six months.
