Abstract

Making a measurement device that measures the water content and oil content of the skin into a portable size such that a female beautician can put it in a bag and easily carry it. Because a freely detachable oil content sample cap can be mounted so that it fits onto a measurement probe on the tip of which has been arranged a water content sensor to detect the amount of water on the surface of the sample under examination, when measuring the amount of water content, the water content sensor on the tip of the measurement probe may be pressed onto the surface of the sample under examination as is, or, when measuring the amount of oil content, after sampling the oil content by mounting an oil content sample cap on the tip of the measurement probe, that oil content sample cap may be removed from the measurement probe and inserted into an oil content measurement hole, and therefore, a water content measurement device and an oil content measurement device may be jointly used with a single measurement probe, and consequently, it is not necessary to provide multiple probes, and the device can be made small-scale.
