Product Description for SL400 Sound Level Meter
The SL400 sound level meter fulfills the requirements for sound level meters of accuracy class 2 according to IEC 61672-1 as well as ANSI S1.4 and is ideally suited for the documentation of machine noise or environmental noise, for work table measurements or expert assessments.
The four-digit display with additional bar graph is very easy to read in any environment thanks to the switchable LCD backlight.
The SL400 sound level meter is a perfect solution for demanding sound level measurements with A- and C-frequency evaluation, fast / slow time evaluation and many other practice-oriented functions.
The handy format, the low weight and the key arrangement optimized for one-hand operation make this measuring instrument an ideal basic equipment for standard measurements in the areas of industry, work and environmental protection.
Additionally, the SL400 is equipped with a live logging function and has a data memory for recording up to 32,700 measured values. The data obtained can be easily transferred to a PC via USB for software-supported analysis. The SL400 can also be attached to the supplied mini-tripod for logging or permanent measuring projects.
Furthermore, an integrated 3.5 mm jack provides connectivity for frequency analyzers or X-Y plotter.
