GRAS 46AG 1/2'' LEMO Pressure Standard Measurement Microphone Set

Enquiry Item

The microphone in the 46AG has a broad working range and reliability that makes it very suitable for coupler and ear simulator setups.

The 46AG is especially suited for audiometer calibration when using an analyzer with a 200 V polarization feature. Regarding temperature range, see the Specifications. Should higher temperature limits be required, we recommend considering the GRAS probe microphones where the microphone and preamplifier can be isolated from the hot source.


Freq range: 3.15 Hz to 20 kHz
Dyn range: 25 dB(A) to 164 dB
Sensitivity: 12 mV/Pa
