GZ0702 audiometer

タイトルまたは説明

GZ****2 audiometer use for pure tone test,be suitable for hospital ENT diagnose and hearing-aid fitting,or clinical/family and outer ambulant hearing test.

Test could proceed by TDH*9 air conduction.test signal including pure tone,pluse voice and warble tone.

GZ****2 audiometer provide *1 air conduction test frequency point, frequency range from **5Hz to 8KHz,dB HL from 0 to **0.

GZ****2 audiometer also provide *1 bone conduction test frequency point, frequency range from **5Hz to 8KHz,dB HL from 0 to *0(the standard is from **0Hz to ***0Hz).

All of the test data result could be automatic switch to pure tone audiogram and calculate patient€™s PTA value automatically.

All of the test data result could be automatic switch to pure tone audiogram and calculate patient€™s PTA value automatically.

The structure of audiometer make it convenient for service,and autotest make it easy to debugging and annual calibration.
