Specification :

JK-NS-5661C Precision Noise Spectrum Analyzer
Performance: meet the requirements of GB/ T3785-1 and IEC61672-1, filter can meet the requires of GB/ T3241 and IEC61260.
Introduction:
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, integrate the 1 / 1 and 1 / 3 octave filters
• JK-PSA-5671A has the function of integral and statistical measurement, direct measurement of Leq-equivalent continuous sound level and LAE-noise exposure level, etc.
• Built-in the 1 / 1 and 1 / 3 octave filter, can manually or automatically select the center frequency of the filter
• JK-PSA-5671A has the function of high capacity of data acquisition, can simultaneously store 800 groups data, datas every hours for 6 days and 22 groups data that is result of filter automatically scanning
• Large LCD, clear and visual read.
• Data storage, print function, can be connected with computer
