Abstract
A method is disclosed for conditioning a gas sensor. The electrode arrangement of the sensor is surrounded by an electrolyte and is partitioned off from the atmosphere by a gas-permeable membrane. The electrode arrangement is introduced into a calibrating gas and the calibrating gas is kept in isotonic equilibrium with the electrolyte. The composition of the electrolyte is not varied substantially while maintaining the operating conditions of the sensor and without having to introduce the sensor into a medium containing the calibrating gas. For this purpose, the membrane of the sensor is covered with a gas-tight and water-vapor-tight overlay, and the isotonic equilibrium is brought about and maintained by means of the gas that diffuses out of the electrolyte through the membrane as far as the overlay.
