SL400 Noise Level Meter with Calibration Certificate
As a Class 2 precision sound level meter, the SL400 is ideal for documenting machine or environmental noise and for conducting measurements in the workplace.
The four-digit display of measured values, along with an additional bar graph, is very easy to read in any environment thanks to the switchable LCD backlight.
With A- and C-weighting, fast/slow averaging, and many other practical features, the SL400 sound level meter is the ideal solution for demanding sound level measurements.
Its convenient size, light weight, and key layout optimized for one-handed operation make this measuring device an ideal staple for standard measurements in the fields of industry, labor, and environmental protection.
The SL400 is also equipped with a real-time logging function and has a data memory capable of storing up to 32,700 measured values. The collected data can be easily transferred to a computer via USB for software-based analysis. The SL400 can also be mounted on the included mini-tripod for logging or long-term measurement.
In addition, the integrated 3.5 mm jack provides connectivity options for frequency analyzers or XY recorders.
