Understanding pH and Conductivity Meters - Benchtop
A laboratory pH and conductivity meter is an essential instrument used to measure the pH level and electrical conductivity of liquids. pH is a measure of the acidity or alkalinity of a solution, ranging from 0 (highly acidic) to 14 (highly alkaline), with 7 being neutral. Conductivity, on the other hand, measures a solution’s ability to conduct an electric current, which is influenced by the presence of ions. These measurements are crucial in various scientific fields, including chemistry, biology, and environmental science, to ensure the accuracy and quality of experiments and processes. The meter typically consists of probes that are immersed in the liquid sample, providing real-time, accurate readings that help in monitoring and adjusting the conditions of the solution being studied.
