Users can either place a sample on the meter’s flat sensor or immerse the meter’s sensor directly into the solution under test. The Elcometer 138 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.

The Elcometer 138 Conductivity Meter includes a convenient salinity conversion indicator.


  • Highly precise measurements can be obtained from a single drop
  • Automatic range switching gives a wide measurement range of 1μS/cm to 19.99mS/cm
  • Out of range and low battery alarms
  • Visual indication when ambient temperature is outside the operating range
