Sound Level Meter with Datalogging SI340

SI340 is an instrument for measuring environmental noise, which can be used in the fields of machine manufacturing, equipment maintenance, architectural design, transportation, environmental protection and health care.

A weight attenuates the low frequency components of the original noise signal of the environment more, simulates the auditory characteristics of the human ear, evaluates the noise size from the hearing, so it is the most widely used, and the weight has less modification to the original noise signal of the environment. Can truly reflect the noise of the environment.

SI340 adds the recording function, which can record all the data in the measurement process.
