Noise Dosimeter

Noise Dosimeter Details:

Detailed Product Description

1.Small size and light weight

2.Fit on shoulder or wrist

3.Measuring noise exposure

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.
