Specification :

JK-NS-6298B Noise Spectrum Analyzer

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
