SMART SENSOR Digital Sound Level Meter – Noise Decibel Meter

The SMART SENSOR Digital Sound Level Meter is a portable precision instrument designed to measure sound pressure and environmental noise levels in decibels (dB). It is suitable for noise monitoring in laboratories, hospitals, workplaces, factories, offices, schools, construction environments and industrial facilities. SMART SENSOR produces several digital sound meter models. Common professional models provide a 30–130 dB measurement range, digital LCD readout and a microphone protected by a foam windscreen. Depending on the model, features can include A/C frequency weighting, FAST/SLOW response, MAX/MIN recording, data storage and USB connectivity. For example, the AS844+ has a 30–130 dB range, 0.1 dB resolution and ±1.5 dB stated accuracy.
