Sound Level Meter SPM483 High-performance measurement device for independent measurements in the fields of sensing and storing sound levels as well as continuous monitoring of sound sources.
High-performance measurement device for independent measurements in the fields of sensing and storing sound levels as well as continuous monitoring of sound sources. This device is particularly used in the sectors of train, road, and air traffic as well as at building sites, during events, and in industrial facilities.
SPM483 is particularly user-friendly and was developed especially for sound level monitoring. Apart from long-term storage of data, it also provides automatic data transfer to a computer or a server. Moreover, the device enables automated customer-specific analyses and evaluations as well as the correlation of different measuring variables at the server side.
