An instrument or device used to measure the conductance or conductivity of a substance, especially liquids and solutions.
From 'conductance' or 'conduct' (Latin 'conducere') plus '-meter' (from Greek 'metron,' meaning measure). Compound scientific instruments typically combine a property name with '-meter' to indicate measurement.
Scientists use conductimeters to measure how salty, pure, or ionic a solution is—because dissolved salt and ions conduct electricity, measuring conductance tells you instantly about the solution's composition without needing to taste it!
