Amplivox ER 75 Electro-Acoustic Ear Simulator

The ER 75 allows daily non biological and objective performance validation of your pure tone audiometer.It will respond automatically at a known threshold over a frequency range of 250Hz to 8000Hz.

Its sophisticated electronics incorporates a hysteresis function to simulate a true patient response. The ER 75 will faithfully reproduce the same levels of threshold on each occasion allowing the operator to determine any drift in calibration or fault on appraisal of test results.

The ER 75 is a small compact battery operated unit which is easily transportable due to its lightweight construction.
