Detailed Product Description 1.Small size and light weight 4.Comply with hearing protction standard Using ARM chip it realizes digital frequency weighting, digital detection and real-time spectral analysis functions. Its special file management system could manage a 2G great capacity storage chip and high reliability makes sure no files damaged when power-off happens, also converting quickly to FAT32 format is available. Noise measurement, sound level recording and precision recording three function can be used at the same time. Meanwhile the pre-amplifier’s rotational structure can meet the installed requirement for measuring standards. |
