First Generation: Purely Optical Instruments
As the original skin tester, it was initially using an ordinary magnifying glass, which needed to be used as a light source by the external ambient light, so the lack of ambient light had a great impact on the test.
Second Generation: Electronic Instruments
With the development of electronic technology, the original optical instruments combined with electronic technology to develop into the second generation of skin testers, which consists of optical components to form the lens, the electronic components to complete the signal acquisition/conversion, and even temporary storage functions, and then through the display instruments (professional color monitor, general-purpose color television) to display.
At this time also appeared a lot of portable tester series, do not need to connect the TV or computer, single function, easy to use.
Third generation: electronic + computer technology
The emergence of computers has greatly advanced the development of society, but also to make the skin tester into the era of intelligence, so that more people can easily grasp the application of skin diagnosis.
No need for professional training: the computer automatic diagnosis and analysis;
Can store customer files, test data, and print diagnostic reports;
Using the USB interface to connect with the computer, without external power supply, can be used with a laptop computer in a variety of environments;
Can be automatic recommendation of the product, and the image of the company can be done to promote the product;
Open analysis system allows users to enter into an intelligent era, so that more people can easily master the application of skin diagnosis. p>Open analysis system allows users to continuously improve and upgrade their systems.
