<p>A soil inspection system (100) comprises an LED light source (210) having a red LED, a green LED and a blue LED, a light receiving sensor (220) having a red PD, a green PD and a blue PD, a sample cell placing unit (230) for placing a circular test tube (T) thereon, an LED light source drive unit (240), a signal processing unit (250), a control unit (260) for controlling the actions of the LED light source drive unit (240) and the signal processing unit (250), an operation unit for calculating the content of an inspection target component by using the absorption spectrophotometry, and a display unit (320) for displaying information containing the content of the inspection target component calculated by the operation unit. Thus, the soil inspection system (100) can perform the soil inspection in situ without using any expensive analyzing device, and can perform the soil inspection on plural kinds of inspection target components with little dispersion of the inspection results.</p> |
