Introduction Kimo DB 300 Sound Level Meter

Kimo DB 300 sound level meter extends the range of classical and intergrator sound level meters. It respects the most recent international standards and brings to the user a high comfort in use. From the simple sound level measurement toe the frequency analysis in real time, Kimo DB 300 covers the most applications in the finding of solutions to get better the noise environment. DB300/2 stores the measurement datasets that can be then transferred in a computer with the LDB23 software.
