Elcometer 138 Conductivity Meter
An instrument consisting of a flat probe, the Elcometer 138 conductivity meter can measure the conductivity of a solution from a single drop to an entire sample.
The user can place the sample on the flat sensor or immerse the conductivity meter probe directly in the solution to be tested. The Elcometer 138 can be used for a wide range of applications, including the concentration of soluble salts, the electrical conductivity (EC) of agricultural solutions or measuring the pollution level of rainwater.
Features :
- Possibility of obtaining highly accurate measurements with a single drop
- Automatically switchable measuring range, wide measuring range from 1μs/cm to 19.99mS/cm
- Out-of-range and low battery indicators
- Visual indicator when ambient temperature is outside working range
