Conductivity meters

Conductivity meters are instruments that measure the electrical conductivity of a solution, reporting how readily it carries current as a proxy for dissolved ion concentration. The reading is taken with a probe that applies a small alternating voltage across two or more electrodes and tracks the resulting current. Of the 249 conductivity meters in the Questpair catalogue, 90 percent of the listings are used, drawn from 17 verified suppliers and distributors across 9 countries. Prices run from EUR 26 to EUR 18.989. New, used and refurbished units all appear, from handheld field probes to benchtop laboratory models that combine conductivity with a pH channel.
