Patent ID: 8256274

Claim:
A sensing device comprising: a sensing sensor provided with a sensing piezoelectric resonator whose natural frequency is varied by an absorption of a substance to be absorbed; an oscillation circuit for oscillating the piezoelectric resonator; a display section for displaying, on mutually differing pages, pieces of time-series data of frequencies of the piezoelectric resonator obtained for each concentration of the substance to be absorbed in solutions, by way of displaying, on mutually differing pages, time-series data for the frequency of the piezoelectric resonator obtained by supplying a fluid containing the substance to be absorbed to first sensing sensor, and time-series data for the frequency of the piezoelectric resonator obtained by supplying a fluid containing the substance to be absorbed at a concentration that differs from the concentration of the substance to be absorbed that was supplied to said first sensing sensor to a second sensing sensor; a unit for setting absorption start points of the substances to be absorbed in the pieces of time-series data; and an editor for performing processing to combine and display at least frequency variation regions in the pieces of time-series data in a state of aligning the absorption start points of the substance to be absorbed, wherein the setting conducted by said unit for setting the absorption start point of the substance to be absorbed is realized when an operator positions a pointer and clicks on the time-series data displayed on said display section.
