The Sound Level Meter / Noise Level Meter is certified in accordance with IEC 61672-1:2013, Class 1 and is ideally suited for professional use in noise monitoring. With a wide frequency range from 10 Hz to 20 kHz and extensive filter options, the device enables precise measurements in almost all areas of application. The frequency weightings A, C and Z as well as the time weightings S (Slow), F (Fast) and I (Impulse) are supported in order to always ensure application-appropriate measurement behaviour.
The Sound Level Meter / Noise Level Meter also impresses with its comprehensive connectivity: Ethernet, WiFi and USB Type-C enable flexible and uncomplicated data transfer. The internal 8 GB memory and optional SD cards with up to 64 GB provide sufficient storage capacity for extensive measurement campaigns. The high-resolution 4-inch TFT touch display ensures intuitive and convenient operation. Measured variables such as Lp, Lmax, Lmin, Leq, Lpeak, LN(1-99) and numerous other useful functions are displayed clearly and in detail, enabling professional detailed evaluation of the measurement results with this Sound Level Meter / Noise Level Meter.
Its wide range of applications makes the Sound Level Meter / Noise Level Meter the ideal solution for environmental noise monitoring, traffic noise analysis, noise exposure assessment, occupational health and safety monitoring and airport noise monitoring.
The software included in the scope of delivery extends the functionality considerably: it enables live data reception via Ethernet or WiFi, access to stored measurement data and the export of results as a PDF report or CSV file. In addition, the display of the measurement parameters can be freely configured within the software, allowing customisation to specific analysis requirements.
