【Features】
Wide frequency range
Wide range of measurement from low-frequency to ultrasonic frequency(1Hz~200kHz) is possible.
frequency
Wide dynamic range
Measurement of high sound pressure level up to 170dB is possible.
Preamplifier integrated microphone
It is also possible to connect directly to analyzer by using BNC cable.
High sensitivity and certain measurement
TYPE7146/4152N20 is a high sensitivity microphone of 500mV/Pa at output voltage.
It is possible to connect directly to analyzer such as FFT and is easy to use enabling to start measurement with low sound pressure level.
