CONTROL METHOD AND SYSTEM FOR IMPROVING FATIGUE OF GAS SENSOR

摘要

The present invention relates to a control method and system to improve fatigue of a gas sensor, wherein the purpose is to shorten a time necessary to recover to an initial state to measure a gas by a semiconductor gas sensor, and to improve sensitivity and reactivity of the gas sensor. The system comprises: an oxygen supply apparatus (10) or an ozone supply apparatus; a measured-gas supply route (30); a valve (40) to select and supply one of a gas supplied from the oxygen supply apparatus (10) or the ozone supply apparatus, and a gas supplied from the measured-gas supply route (30); and a measurement space body part (50) having a semiconductor gas sensor (60) installed therein.
