Lx-hs6123 is a multifunctional electroacoustic product comprehensive tester with computer. It can test the sensitivity, frequency response curve, rated impedance and working current of both ears and microphone in one time. Instrument test accessories are flexible and varied, and can be configured into four test instruments as shown in the figure.

The characteristics of

1. Three test curves and three backup curves can be displayed in different colors on the same screen (binaural + microphone).

2. The tolerance boxes can be set for each test curve respectively. The setting mode can be drawn directly or from the sample curve according to the technical requirements of the product under test. The tolerance box frequency range can be set arbitrarily in the test frequency range.

3. Test results can be saved, printed or pasted onto Windows for processing.

4. Full Chinese interface, detailed operation tips, stable and reliable performance, simple and convenient operation, suitable for the earphone product and all kinds of electro-acoustic device unit test.
