It should be noted that during the measurement of the systemic pesticide residue level of the crop to be measured in this embodiment, the metal probes 1421 and 1422 and the light guide column 1413 are inserted into the interior of the crop, especially the xylem. Therefore, the light emitted from the light transmitter 1411 reaches the inside of the crop to be measured, especially the xylem, through the light guide post 1413, and is reflected by the light guide 1414 and then received by the light receiver 1412. Therefore, the optical sensor 141 ′ has higher availability and accuracy than the optical excitation response value received by the optical sensor 141 of the first embodiment. Nevertheless, as long as the purpose of receiving the optical excitation response value of the inside of the crop to be measured, especially the xylem, and the electrochemical response value of the electrical sensor 142, especially the xylem, can be achieved, this creation is not here Limitations are placed on the arrangement of the optical sensor 141 'and the electrical sensor 142.
