Introduction:

Performance:meet the requirements of GB/T3785-2 and IEC61672-2, filter can meet the requirenments of GB/T3241 and IEC61260-2.

Aplication: be used for industrial noise measurement of various machines, vehicle,shipping and electrical.Suitable for the areas of industrial enterprises,environmental protection,industrial hygiene,teaching  and scientific research

Characteristics:

·Instead of some traditional sound level meters, its stability and reliability was greatly increased by using digital detector technology

·Has the function of integral and statistical measurement, direct measurement of Leq-equivalent continuous sound level and noise exposure level, etc.

·Built-in the 1 / 1 octave filter, can manually or automatically select the center frequency of the filter

·Has the function of high capacity of data acquisition,can simultaneously store 800 groups data,datas of every hours for 6 days and 12 groups data

that is result of filter automatically scanning

·Test function with reverb

·Large LCD,clear and visual read

·Data storage,print function,can be connected with computer
