Conductivity/Total Dissolved Solids
Conductivity and TDS Testers come in a variety of styles. We have versions with graphite sensors which reduce polarization effects that occur with amperometric measuring methods. A key feature is temperature compensation, since EC/TDS measurements are very sensitive to temperature changes. Hanna Instruments uses an exposed temperature probe for near instantaneous measurement, resulting in a faster response time. Other features include a multi-level LCD to display EC or TDS along with temperature, adjustable EC to TDS conversion factors, and adjustable temperature compensation coefficient.
