Spacious test chamber with great acoustic properties

The Primus HIT Pro test chamber is very spacious and has excellent properties. The noise reduction of external sources is extremely good which, in combination with the linearity of the acoustics, will give you more accurate test results. 

Easy placement of hearing instruments

Having a large work area in combination with the smart hearing instrument clip makes it easy for you to place any type of hearing instrument. For your convenience a RIC adaptor gives you an effortless connection of open fit hearing instruments.

Quick FM verification & RECD measurements

Extended cables and the clever placement of sockets helps you do FM verifications even faster. RECD measurements can be performed easily with the built-in protocols.

The simplicity and intuitive design supports an efficient workflow and the discrete labelling and colour coding of sockets guides to correct usage.

Easy positioning of hearing instruments

No need to fumble with different holders and clips, when the smart and simple clip easily holds any type of hearing instrument in the correct position.

The clip can be removed if needed, and you can perform tests on both right and left side. 

Discrete and surprisingly spacious built-in compartments will help you store your accessories, such as battery packs, spare parts, hearing instruments etc, right where you need them.

Left and right LED indicators

Coloured LED indicators will help you operate the Primus HIT Pro unit. When connected to the PC, a green light appears when the Primus HIT Pro is ready for use. For your convenience, a red or a blue light shine, when tests are run on either the right or the left side.

The elegant front button will let you start and stop tests with one simple click when the Primus HIT Pro test chamber is closed. 

You can perform full featured technical measurements that can be run as automatic test sequences in accordance with European standards – IEC and ANSI standards are both supported.
