(TYPE 1)

About the product

Preamplifier integrated microphone compatible with IEPE can be connected directly to FFT analyzer or other analyzers, enabling to measure with highly accurate resolution at low costs.
Long-term stability realized by accelerated aging process under 360℃ enables to use under 100℃ or higher.
Condenser microphone is to be used for measurements of sound presser level with high resolution over wide frequency range.
Varieties of microphone diaphragm diameter 1,1/2, 1/4, 1/6, 1/8 inch and corresponding frequency characteristics would best support measurements of various purposes.
