Inventis Clarinet light, small and sturdy metal probe


Clarinet is a clinical middle ear analyzer, featured with all the tests needed for an accurate investigation of disorders.
Automatic and manual tympanometry, acoustic reflex threshold, decay and latency examinations, ETF for intact and perforated eardrums, high frequency and multi-component tympanometry.


Clarinet features an extremely light, small and sturdy metal probe, which can be very rapidly disassembled and cleaned. The probe is connected to the small Control Box, through which you can select the ear and start the exam.


The speed of the pump is incredible: the sweep speed can reach 600 daPa/sec, without compromising on accuracy and precision of tympanogram plots. The pump features an endless airflow technology, improving the execution of the test when the seal is not optimal.


Simply connect Clarinet to a USB port on your computer (no driver needed), and you can transfer exam results into your Maestro or Noah database. With the live view feature, you can have a wide view of the examination in progress on the computer display.
