Main features：
Complies with the requirements of IEC standard Type 1 instruments;
Directly measure the admittance of the human ear and draw the tympanum and eustachian tube diagrams;
Display, store, and retrieve test results directly from the host without the need for a computer, and print them with a built-in printer;
The computer controls the host to work and print through the USB interface.
