| Zusammenfassung: | The invention belongs to the technical field of impedance testing and particularly relates to a skin impedance tester. The skin impedance tester is good in testing effect and stability. The skin impedance tester comprises a frequency synthesizer, an amplification filter portion, a voltage control current source, a digital display portion, a terminal variable-frequency portion, an A/D conversion portion, a signal conditioning portion, a low-pass filtering portion, a gain amplification portion and a level conversion portion and is structurally characterized in that the frequency synthesizer is connected with the amplification filter portion, the voltage control current source, the digital display portion, the terminal variable-frequency portion, the A/D conversion portion and the signal conditioning portion respectively, and the low-pass filtering portion, the gain amplification portion and the level conversion portion are connected in sequence. |
