The sound level meter and calibrator are the components of our sound level analysis system. The exponential time-weighted sound level is measured using a sound level meter. With an LCD panel and an instantaneous sound level, it is dynamically developed. This further improves the readability, stability, and reliability of the instrument by measuring and displaying the results in digital display mode. Solid state integrated circuitry is used in the calibrator to deliver precise and consistent performance. It is quite sensitive while calibrating microphones.
