G.R.A.S. low noise microphone systems are state of the art transducers for laboratory measurement of products with very low noise emissions and allow measurement at and below the threshold of human hearing.
- 1” and 1/2” microphone systems
- Externally polarized and signal conditioned
- Noise floor from 0 dBA to 7 dBA
- 1 V/Pa to 750 mV/Pa sensitivity
- LEMO or BNC Outputs
