SONOMETER - DECIBELMETER BENETECH DIGITAL SOUND LEVEL METER The sonometer has been designed to meet safety requirements for measurements in engineering, medicine and industry. It is suitable for measuring sound intensity in various environments such as factories, offices, street traffic, workstations, at home, but also for checking the sound quality of audio systems. FEATURES AND FUNCTIONS OF THE DECIBELMETERS: Sound intensity measurement; Equipped with type A and C weighting filters. Two measurement modes: fast and slow. MIN/MAX value reading; Data storage: function of saving up to 43000 data files as well as reviewing and deleting them; Automatic power-off function after a time of inactivity; Freezing measurement results (HOLD function); Backlit LCD display; Line graph: Visual display of noise data changes; USB charging and computer communication: Connecting to a computer via USB allows for data download, real-time analysis of collected data, and printing graphs and data. Displays date and time; Manual or auto shut-off; Configurable 3-color alarm function; Auto shut-off function with the ability to disable it; Possibility to calibrate the device using the potentiometer on the back of the device. The device meets the requirements of IEC PUB 651 TYPE 2 and ANSI S1.4 TYPE2 standards. CORRECTION FILTERS: Filter A corresponds to the frequency sensitivity of the human ear . It is used when measuring the ambient noise level. Filter C with flat characteristics, 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 average noise level measurements. MANUAL CALIBRATION POSSIBILITY Using the potentiometer located on the rear of the housing and a standard acoustic calibrator. PC SOFTWARE: Connecting to a computer via USB allows to download data, analyze collected data in real time, and print graphs and data. HOW THE HUMAN EAR HEARS SOUND: 1~15dB - absolute silence 15~20dB - silence 20~40dB - whisper 40~60dB - normal conversation 60~70dB - noise 70~90dB - loud noise 100dB and more - noise hazardous to health TECHNICAL SPECIFICATION OF THE SONOMETER Device dimensions: 160 x 56 x 31mm Weight: 120g (with batteries) Measurement range: 30~130dB(A), 35-130dB(C) Accuracy: ± 1.5 dB Operating Frequency: 31.5Hz~8500Hz Measurement Resolution: 0.1 dB Weighting Filters: A/C Data Storage: 43000 records Measurement Frequency: FAST(8/SEC) SLOW(1/SEC) Microphone: 1/2 inch polarized condenser Operating Conditions: Temperature: 0 ~ 50°C , Humidity: 10 ~ 80% RH Storage Conditions: Temperature: -10 ~ 60°C , Humidity: 10 ~ 70% RH Rated Current : 70mA Working time: 8h (alkaline batteries) Charging time : 1.5h Power supply: 3.7V/1000mAh lithium battery DESCRIPTION OF THE DEVICE ELEMENTS: Sponge cover (prevents errors caused by wind).
