Professional control of environmental noise

Sound level measuring device SL400 with data logger function

Owing to the factory-made ISO calibration, the integrated live logging function and the supplied analysis software, the universally applicable sound level measuring device SL400 is ideally suited for the professional control of workplace, industrial and environmental noise. Moreover, the SL400 can only be recommended for expert services, for the measuring device meets the requirements for sound measuring devices of accuracy class 2 according to IEC 61672-1 and ANSI S1.4.

The SL400 allows for a separate weighing of type A and type C frequencies. While the A frequency corresponds to the sound pressure perception of the human ear, the C frequency focusses low-frequency components of a sound. Depending on the requirements you can use the fast/slow time weighing feature of this professional measuring device to switch over from measuring once per second (slow) to once every 125 milliseconds (fast).

Sound level measuring device SL400 – for professional expert documentations

The four-digit measuring value display of the SL400 with an additional bargraph indicator can easily be read in every environment thanks to the LCD background illumination. The supplied software allows, among other things, for live recording of the measured values with real-time indication, a graphic or tabular representation of the measured values including an option to print them out as X-Y diagrams or tables, as well as a zoom function and an export possibility in Excel format.

The SL400 is further equipped with a live logging function and enough data memory to record up to 32,700 measured values. For a software-supported analysis the measured data can simply be transferred to a PC via USB. For logging or non-stop measurements the SL400 can be fixed to the supplied mini tripod. Thanks to the integrated mains connection and supplied power adapter, it is also possible to switch over from battery- to mains-powered operation for time-consuming long-term measurements. Moreover, an integrated 3.5 mm jack socket provides the SL400 with connections facilities for frequency analysers or x-y plotters.
