    摘要: A sensor apparatus comprising a portable sensor body. The sensor body includes a support with one or more sensing electrodes, and electric connections connecting to the electrodes. The apparatus further includes a storage container, designed to receive at least a part of the support that includes one or more of the electrodes, for storing the sensor body. The container comprises a deformable wiper. The wiper is shaped correspondingly with the support and electrodes thereof, to wipe liquid (and/or other materials contained therein) off the support responsive to inserting the latter in the container and, conversely, responsive to de-inserting the support from the container. Mutually corresponding parts of the sensor body and the container may form a fastener, so as to be able to create a non-permanent joint between the sensor body and the container responsive to the sensor body being fully inserted in the container.
