Our highly recommended ER75 Electro-Acoustic ear simulator is the
perfect partner to objectively validate your audiometric equipment.
When
conducting audiometry it is essential to ensure the accuracy of your
instrument. Completely automatic, the ER75 will
validate your Amplivox audiometer and respond in a consistent manner to produce
repeatable thresholds over the frequency range of 0.25kHz to 8kHz. Daily checks
can be easily conducted before the day begins, as the entire validation is completed
in under 5 minutes and you can be assured that your equipment is operating at
optimum performance.
The ER75
is the ideal for use within an occupational health accreditation scheme.
