The first thing to consider when choosing a conductivity meter is the range you need to measure. Conductivity meters are available in a variety of ranges, from low to high. If you only need to measure low levels of conductivity, a low-range meter will suffice. If you need to measure high levels of conductivity, you will need a high-range meter. The range you need will depend on the type of liquids you normally test.
Another important consideration is the accuracy of the conductivity meter. Conductivity meters are available in a variety of accuracy levels, from 0.1% to 1.0%. The accuracy you need will depend on the application for which you are using the meter. If you need to measure very precise levels of conductivity, a higher level of accuracy will be required.
Un medidor de conductividad está provisto de una sonda, que es insertada en el líquido a medir, luego el medidor aplica un voltaje entre dos electrodos dentro de la sonda. El equipo mide la caída del voltaje de la solución, la cual es provocada por la resistencia eléctrica. Y luego el medidor de conductividad convierte la lectura en S/cm, donde el valor indica la cantidad total de sólidos disueltos, es esta cantidad de sólidos disueltos que puede atravesar la fibra de vidrio. Es decir, el conductivímetro funciona con una corriente alterna para evitar que ocurra una reacción en la sustancia a analizar o que exista algún efecto sobre las placas del conductivímetro.
