frequency domain measuring devices, and discloses a portable electrochemical impedance detection auxiliary device and a control method, which comprises a shell, the shell has a shielding function, the shell is internally provided with a power supply module, a main control module, a
temperature control and
electrode chamber module, and an impedance
detector connection module, the surface of the shell is provided with a man-
machine interaction module and an impedance meter connection terminal, the power supply module is used for supplying power to the whole device, the
temperature control and
electrode chamber module and the man-
machine interaction module are electrically connected with the main control module, the main control module is used for transmitting information with the man-
machine interaction module, and the
temperature control and
electrode chamber module is controlled to perform a constant temperature and variable temperature task at a
fixed time. The application optimizes electrode wiring, constant temperature and variable temperature operations into simple electrode loading and unloading and man-machine interaction, and reduces the complexity of operation. The device integrates temperature control, electrode connection,
electromagnetic shielding and other functions, and better guarantees the accuracy and stability of impedance measurement signals.
