Assignee: ROHM CO., LTD.
Field: Measurement (Instruments)
Classification: CPC G  Y | IPC G

Claim 3:
4. The gas concentration measurement system according to claim 1, wherein
the limiting current-type gas sensor includes a first limiting current-type gas sensor element and a second limiting current-type gas sensor element, wherein each of the first limiting current-type gas sensor element and the second limiting current-type gas sensor element is a duplicate of the limiting current-type gas sensor element,
the current detector includes a first current detecting element corresponding to the first limiting current-type gas sensor element and a second current detecting element corresponding to the second limiting current-type gas sensor element,
the first current detecting element is configured to acquire a limiting current value of the first limiting current-type gas sensor element when the first voltage is applied to the first limiting current-type gas sensor element as the first limiting current value, and
the second current detecting element is configured to acquire a limiting current value of the second limiting current-type gas sensor element when the second voltage is applied to the second limiting current-type gas sensor element as the second limiting current value.
