Description

Measuring instrument to obtain the electrical charge passed in an experiment, or to produce a known amount of substance in a titration.

Comment	Modern instruments for measuring trace water by Karl Fischer titration use the passage of a measured charge to produce iodine from iodide solution. They are known as Karl Fischer coulometers [en] The silver coulometer is a primary reference measurement procedure [VIM 2.8] for charge and current. By weighing the mass of silver deposited in a known time at constant current, the charge and current are calculated from Faraday’s laws of electrolysis [en]
