DUBAN DB30-6228F Noise Spectrum Analyzer Measurement range 25dB~ 130dB

Introduction

DB30-6228F noise spectrum analyzer is a kind of universal sound level meter that measures exponential time weighted sound level, and is the integral average sound level meter that can measure the average sound level of time and the integral sound level meter that measures sound exposure, it can also measure the cumulative percentage sound level (statistical sound level), is suitable for all kinds of industrial environmental noise measurement and environmental noise survey measurement, especially suitable for spectrum analysis of noise for sound level measurement of environment, machinery, traffic, ships and other noise; It is suitable for industrial environmental protection, construction, health, teaching and scientific research and other departments.

Features

• Its performance meets the requirements of GB/T 3785 and IEC 61672-2002 for 2-level sound level meters, JJG 188-2017 standards, and also meets the requirements of IEC1260 and GB/T 3241-1998 for octave filters and 1/3 octave filters.

• It has built-in 1/1 octave and 1/3 octave filters. Manual and automatic sweep measurements are available. 12 groups of automatic sweep measurement data can be automatically saved.

• With integral and statistical functions, the single group measurement can reach 800 groups, and the whole time measurement can reach 6 days. The stored data can be accessed and printed. The collected data can be checked when the hourly measurement is paused.

• There are three levels of time weighting: fast (F), slow (S), and pulse (I).

• The digital detection technology is used to replace some traditional sound level meters in the past, and the stability and reliability are greatly improved.

• The large screen display is adopted, and the display is clear and intuitive. There is a dynamic scale display.

• Optional Bluetooth printer for measurement data printing.

• USB cable and Bluetooth data output are used to communicate with the PC.
