Overview
The noise spectrum analyzer is a multi-functional sound level meter, which can be used for the measurement of exponential time weighted sound level, time average sound level, sound exposure and cumulative percentage sound level (statistical sound level). It is suitable for noise measurement and environment noise census in various industrial environments, especially for noise spectrum analysis and sound level measurement in the fields of environment, machinery, transportation, ships, etc. It can also be used in industrial environmental protection, construction, teaching and research and other fields.
Features
The performance meets the requirements of GB/T 3785 and IEC 61672-2002 standards for 2-level sound level meters, and meets the JJG 188-2017 standard.
2. With integration and statistical functions, a single measurement can store up to 800 sets of data, continuous measurement up to 6 days.
3. The stored data can be easily viewed and printed, and the user can check the collected data when the measurement is suspended.
4. Provide the choice of fast (F) and slow (S) two time weighting gears.
5. Adopting digital detection technology instead of traditional sound level meters improves Stability and Reliability.
6. Equipped with a large screen display, the information is clear and intuitive, and has a dynamic scale display function.
7. Optional Bluetooth printer, easy to print measurement data.
8. Support USB cable and Bluetooth data output, can communicate with PC, easy data transmission and analysis.
Principle
The product uses digital detection technology to collect sound signals through microphones, and after processing with frequency weighting (A weighting, C weighing, linear) and time weighting (fast, slow and pulse), the sound level is measured and the data is stored.
Applications
Environment, machinery, transportation, shipbuilding, industrial environmental protection, construction, teaching and research
Standards
GB/T 3785、IEC 61672-2002、JJG 188-2017、IEC61672
