Elcometer-138-conductivity-meter

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.

The Elcometer 138 Conductivity Meter features:

  • 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
