GRAS 46AZ 1/2" CCP Free-field Standard Microphone Set, Low Frequency

Enquiry Item

The 46AZ is a free-field microphone set and as such optimized for all acoustic applications, where the location of the main sound source is known and the microphone can be pointed directly at it ensuring 0° incidence.

The low frequency range makes it ideal for measuring low frequency sound from e.g. wind mills.

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 dB): 0.5 Hz to 20 kHz
Dyn range: 17 dB(A) to 138 dB
Sensitivity: 50 mV/Pa
Use: For low frequency acoustic diagnostics
