LEADMED
>> Information
Salinity sensor adopts new four-electrode structure design, automatic temperature compensation, suitable for surface water, groundwater, industrial water, waste water and other application.

>> Characteristics
Measurement of conductivity and temperature, output specific conductivity, salinity and total dissolved solids and other calculation parameters;
Four-electrode measurement principle, no passivation, more accurate;
Support kinds of installation methods, can use different shell materials, thus suitable for many application;
Automatic range selection, automatic temperature compensation;
Strong, corrosion resistance, anti-interference;
Wide measurement range;
Fast response time.
