Electrical Conductivity Sensors - Greenspan EC250, EC3000

The Greenspan Analytical Electrical Conductivity Sensors provide highly accurate conductivity measurements in a wide range of hydrological applications.

Its toroidal design brings the benefits of exceptional reliability and resistance to chemicals .  It provides highly accurate temperature compensated measurements. 

Field conductivity measurements in ionised solutions have traditionally been inaccurate due to unwanted temperature and electrode effects. This sensor substantially eliminates these sources of error.  A larger sized toroidal sensor element uses the free ions in solution as a conductive path between two shielded ferrite transformer cores.

This system eliminates errors caused by electrode degradation.  An advanced compensation algorithm in the on-board microprocessor substantially reduces system non-linearity and temperature drift errors.
