WebThe principle of ozone measurement by the electrochemical sonde is based on the titration of ozone in a potassium iodide (KI) sensing solution according to the redox reaction [I]. (An exception is the carbon–iodine ozone sensor, which uses potassium bromide (KBr) instead of potassium iodide (KI). Potassium bromide (KBr) is a salt, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries, with over-the-counter use extending to 1975 in the US.
