Specific embodiment
Below in conjunction with the drawings and specific embodiments to the utility model proposes a kind of moisture of skin evaporation rate tester
It is described in further detail.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It needs
Bright, attached drawing is all made of very simplified form and using non-accurate ratio, only conveniently, lucidly to aid in illustrating
The purpose of the utility model embodiment.
With reference to Fig. 1, a kind of moisture of skin evaporation rate tester, for measuring moisture of skin evaporation rate, including data
Acquisition unit, data processing unit, interactive unit and shell 8.Data acquisition unit includes humidity sensor 2 and reference capacitance again
4.This tester is described further below in conjunction with specifically used method, on the skin by the measurement end pressing of shell, with skin
Skin collectively constitutes a closed measurement cavity 1, and humidity sensor 2 is arranged in the measurement cavity 1, for acquiring surveyed region skin
The relative humidity information in airtight cavity that skin and apparatus measures end are formed.Reference capacitance 4 is used to measure the interference value of environment, goes
Except environmental factor error caused by capacitance measurement.Since the measurement of capacitor is easily influenced by environmental factor, if by humidity
The measurement result of sensor 2 directly uses, then uncertain larger.
Monitoring result is impacted to reduce or eliminate external environment as far as possible, is joined in the utility model with reference to electricity
Hold 4, the moisture of skin that the ratio of the capacitance of institute's measuring moisture sensor 1 and 4 measured value of reference capacitance is converted evaporates speed
