Problem to be solved: to provide a measuring apparatus, a measuring method and a measurement system capable of stably acquiring the living body information of the subject.The measuring apparatus 100 includes a sensor group 120 having a plurality of sensors 200 having a light emitting portion 220 for emitting the measurement light, a light receiving portion 230 for detecting scattered light corresponding to the measurement light, and a package 210 in which the light emitting portion 220 and the light receiving portion 230 are mounted, and is based on scattered light The control section 400 is provided for detecting the biological information of the examiner.The control part 400, for each of the plurality of sensors 200, operates the sensors 200 in order to detect the pulse wave as the biometric information of the subject, the maximum wave height of the pulse wave, or the fact that the characteristic point of the pulse wave shows the most clearly, and is detected from the plurality of pulse waves detected as a reference Not even one pulse wave to choose.Diagram【課題】被検者の生体情報を安定して取得できる測定装置、測定方法及び測定システムを提供する。【解決手段】測定装置１００は、測定光を射出する発光部２２０と、測定光に応じた散乱光を検出する受光部２３０と、発光部２２０と受光部２３０とが実装されるパッケージ２１０とを有するセンサ２００を複数含むセンサ群１２０と、散乱光に基づいて被検者の生体情報を検出する制御部４００とを備える。制御部４００は、複数のセンサ２００それぞれについて、各センサ２００を順次に動作させて被検者の生体情報として脈波を検出し、脈波の波高が最大であること、又は、脈波の特徴点が最も明確に表れていることを基準として、検出された複数の脈波から少なくとも１つの脈波を選択する。【選択図】図１
