Integrating Sound Level Meter sound level meter consists of a calibrated microphone, electronic circuits, and a display. The microphone detects small air pressure variations associated with sound and converts them into electrical signals. The aforementioned signals are then processed using the instrument's electronic circuitry A main interface can display most useful information of the instrument states and basic noise result here is a three profiles interface display independently result that measured in parallel.

• 100dB dynamic range
• Three profiles display
