DECIBELMETTER SONOMETER SOUND LEVEL METER NOISE VOLUME 30-130dB

✅ SONOMETER - DECIBLE METER

BENETECH DIGITAL SOUND LEVEL METER

The sonometer has been designed to meet safety requirements for measurements in engineering, medicine and industry.

It can be used to measure sound levels in various environments such asfactories, offices, street traffic, workstations, at home, but also to check the sound quality of audio systems.

✅ FEATURES AND FUNCTIONS OF THE DECIBLE METER:

• Sound intensity measurement;

• Equipped with type A and C correction filters.

• Two measurement modes: fast and free.

• MIN/MAX reading;

• Data storage: function of saving up to 43,000 data files, viewing and deleting them;

• Automatic power-off function after a period of inactivity;

• Holding measurement results (HOLD function);

• Backlit LCD display;

• Line graph: Visual display of noise data changes;

• USB charging and computer communication: Connection to a computer via USB allows data download, real-time analysis of collected data, and printing of graphs and data.

• Displays date and time;

• Manual or automatic power-off;

• Configurable 3-color alarm function;

• Automatic power-off function with the possibility of disabling it;

• The device can be calibrated using the potentiometer on the back of the device.

• The device meets the requirements of IEC PUB standards 651 TYPE 2 and ANSI S1.4 TYPE2.

✅ EQUALIZATION FILTERS:

Filter A corresponds to the frequency sensitivity of the human ear. It is used for measuring the ambient noise level.

The C filter with a flat characteristic is used to measure the level of noise generated by mechanical devices.

The device has a measurement function in Fast Mode for regular measurements and in Slow Mode for measuring the average noise level.

✅ MANUAL CALIBRATION POSSIBILITY

Using the potentiometer on the back of the housing and a standard acoustic calibrator.

✅ PC SOFTWARE:

Connection to a computer via USB allows downloading data, analyzing collected data in real time, and printing graphs and data.
