Probe tube placement made easy

Inserting the probe tube in the ear canal can be a challenging part of the real ear measurement process. If inserted too short into the ear canal your measurements become inaccurate. Inserted too deep you may, to the discomfort of your client, touch the ear drum. The REM probe holder enables uncomplicated positioning of probe microphones, regardless of ear size and ensures correct placement for more accurate real ear measurements without worry.


Make hearing aid fitting faster and easier with incorporated verification

Close integration between Primus and hearing instrument fitting software simplifies and streamlines the verification process and allows you to accomplish fast and accurate verification. Using Primus, you can adjust the hearing instruments automatically and make an automated fit to a prescriptive target directly in hearing instrument fitting software. Primus is incorporated into ReSound, Beltone, Interton, Oticon, Bernafon and Sivantos fitting software.
