Product Data With the new Audiometer option in the Sound Analyser Nor140 we are offering a complete Audiometer-Calibration Kit. The Class 1 Sound Analyser Nor140 (approved acc. to EN-ISO 61672) measures and displays not only the sound pressure level, but in addition the exact frequency and distortion. This means you no longer need to perform separate measurements to verify the frequency and distortion values, as the meter presents the nal value. It also means that you do not need an additional frequency counter and distortion meter. The small, lightweight (approx. 400 g) and easy-to-use Nor140, is an optimal eld-solution. All important functions for performing the audiometer calibration are now covered using only the Nor140 with the appropriate couplers to the audiometers. The Nor140 accepts most available ear simulators. We are able to offer a complete system for audiometer calibration comprising of the Nor140 itself plus the Articial Ear Type 43AA (IEC 60318-1) and Type 43AF (IEC 60318-3) from G.R.A.S.
