SL 4005
Digital Sound Level meter with A, C & F weightings, upto 130dB measuring range and built in calibration mode.
Features:
- Data storage
- Built in calibration mode
- A,C & F frequency weightings
- Measuring level and time level selection
Applications:
Sound level meters are commonly used in noise pollution studies for the quantification of different kinds of noise, especially for industrial, environmental, mining and aircraft noise.
Measuring Principle:
Sound level meter measures the sound level in logarithmic scale. There is a diaphragm in the microphone which responds to changes in air pressure caused by sound waves. This sound pressure is converted into logarithmic scale and displayed.
