UT352 - sound level meter (sonometer)

Description

Sound level meter (sonometer) that can measure the noise level in dB. Depending on the application, modes A or C can be selected. Filter A corresponds to the frequency sensitivity of the human ear and is used to measure the ambient noise level. The C filter with a flat characteristic is used to measure the noise level generated by mechanical devices. UT352 consumes very little energy and can run continuously for up to 20 hours. They are suitable for measuring industrial and environmental noise levels.
