DUBAN DB30-6228LEQ integrated sound level meter, integrated + statistical 1-stage noise meter

DB30-6228LEQ

Integrating sound level meter

Level 1 integral sound level meter, in line with GB/T 3785, IEC 61672-2002 and JJG 188-2017 standards. With integral and statistical functions, it can store 800 sets of data for continuous measurement up to 6 days. Support A, C, Lin Frequency weighing, Measurement range 25dB (A)~ 130dB (A).

Applications

The integrating sound level meter can not only be used as a general sound level meter for measuring exponential time weighted sound levels, but also has the function of an integrating average sound level meter for measuring time average sound levels. It can also be used as an integrating sound level meter. For measuring sound exposure, it can even measure cumulative percent sound levels (statistical sound levels). This instrument is suitable for noise measurement in various industrial environments and environmental noise census measurements, and is especially suitable for situations where noise spectrum analysis is required. Used for sound level measurement of various types of noise in the environment, machinery, transportation, ships, etc., and is widely used in many fields such as industrial environmental protection, construction, health, teaching and scientific research.

Features

This integrating sound level meter has the following features:

• The performance complies with the requirements of GB/T 3785 and IEC 61672-2002 standards for Class 1 sound level meters, and also complies with the JJG 188-2017 standard.

• Equipped with integration and statistical functions, it can store up to 800 sets of data in a single measurement, and continuous measurement can last up to 6 days. The stored data can be easily retrieved and printed, and users can also check the collected data when the full-time measurement is paused.

• Provides the choice of two time-weighted gears: fast (F) and slow (S).

• Digital detection technology is used to replace the traditional sound level meter, thereby significantly improving stability and reliability.

• Equipped with a large screen display, the information is clear and intuitive, and supports dynamic scale display.

• Users can choose to use a Bluetooth printer to print measurement data.

• Supports data output via USB cable and Bluetooth to facilitate communication with PC for data transmission and analysis.
