Incorporating a flat sensor, the Elcometer 138 Conductivity Meter can measure the conductivity of a solution from a single drop of a sample

Users can either place a sample on the conductivity meter’s flat sensor or immerse the meter’s sensor directly into the solution under test. The Elcometer 138 Conductivity Meter can be used for a broad range of applications, including soluble salt concentrations, the electric conductivity (EC) of solutions used in agricultural operations, and measuring rainwater pollution levels.
