SONOMETR - Decibel Meter with USB Interface

Professional digital decibel meter with two correction characteristics, A and C. It meets the requirements of IEC651 ANSI and S1.4 TYPE2 standards. A filter is used to measure ambient noise levels (equivalent to the sensitivity of the human ear). C filter, with a flat characteristic, is used to measure noise levels generated by mechanical devices.

This meter allows recording of up to 4700 measurements in the device memory (data logger). This data can be read after connecting the decibel meter to a PC, following installation of the software supplied with the device. The program allows not only retrieval of data from the device memory, but also real-time monitoring of measurements and archiving them directly on the computer.

The decibel meter has a suitable calibration port and AC/DC analog output for connection to external devices, such as oscilloscopes. It is designed for tripod mounting. The package includes an elegant plastic case for easy transport and storage, a manual in Polish, batteries, a USB cable, a microphone cover, and an output cable.
