These disposable Real Ear Measurement (REM) probe tubes are essential supplies for audiologists and hearing care professionals performing hearing aid fittings and verification. Sold in a convenient 50-count pack, the tubes are thin, flexible silicone tubes inserted into the ear canal alongside a hearing aid to measure sound levels at the eardrum.

Real Ear Measurement is the gold standard for verifying that a hearing aid is delivering the precise level of amplification needed at every frequency. The probe tube is inserted to a typical depth of 28–30 mm from the ear canal opening, allowing a connected microphone to capture in-ear measurements and compare them against target amplification values. REM is recommended by both the American Speech-Language-Hearing Association (ASHA) and the American Academy of Audiology (AAA).

Each tube includes marker rings to indicate correct insertion depth during measurement. The tubes are made from biocompatible, latex-free materials and are designed for single-use, disposable applications. They are universally compatible with all major REM measurement systems, including Audioscan, Siemens, Madsen, MedRx, Interacoustics, Inventis, and Frye Systems equipment. The 50-count pack provides a cost-effective supply for a busy hearing aid fitting practice.
