A set of sensors

摘要

A sensor includes an analyzing part (2, 3) and a passage (1) having two ends. One end of the passage (1) is connected to the analyzing part (2, 3). The other end of the passage (1) is closed before use so that the inside of the passage (1) and the analyzing part (2,3) is sealed to prevent a contact with the outside. When the sensor is to be used, the other end of the passage (1) is opened so as to provide an inlet (9) for a sample. <IMAGE>
