COMPONENT CONCENTRATION METER, COMPONENT CONCENTRATION MEASUREMENT METHOD, SHIPPING INSPECTION SYSTEM, AND HEALTH MANAGEMENT SYSTEM

摘要

An component concentration meter (10) includes an output unit (20) that outputs an electromagnetic wave to an object to be measured (50), a detecting unit (30) that detects the property of the electromagnetic wave passed through the object to be measured (50) under a first condition and under a second condition in which the temperature of the object to be measured (50) is different from that under the first condition, and a concentration determining unit (40) that determines the concentration of a target component contained in the object to be measured (50), based on a property difference which is a difference between the properties of the electromagnetic wave detected by the detecting unit (30) under the first condition and under the second condition and a difference between the temperatures of the object to be measured (50) under the first condition and under the is second condition.
