Main highlights

The SL400 is also equipped with a live logging function and has a data memory to record up to 32,700 readings. The determined data can be easily transferred via USB to a PC for software-supported analysis.
The SL400 comes as a complete set including ISO calibration certificate, clip-on wind protection, mini tripod, power supply, USB cable, analysis software, service tool, instruction manual and transport case.
In addition, the SL400 allows you to assess A and C frequencies separately. While the A frequency corresponds to the sound pressure perception of human hearing, the C frequency focuses low-frequency components of a sound. The SL400's four-digit readings display with additional bargraph display is very easy to read in any environment thanks to the LCD backlight.
For logging or continuous measurement applications, the SL400 can also be attached to the included mini tripod. The integrated mains connection allows you to easily switch from battery to mains power operation for time-consuming long-term measurements via the included power supply. In addition, a 3.5 mm jack socket integrated on the SL400 offers connection options for frequency analyzers or X-Y writers. An ISO calibration certificate is already included with the SL400.
As a sound level meter according to accuracy class 2, you are always well equipped with the SL400, whether for documenting machine noise, environmental sound emissions or for workplace measurements. Depending on your requirements, you can change the measurement time with this professional measuring device from a second measurement interval (slow) to a measurement every 125 milliseconds (fast) via fast/slow time evaluation.

The BS30WP sound level meter impresses with its high measurement sensitivity and is therefore particularly recommended for precise determination of already low sound levels from 35 and up to 130 dB(A). The meter is ready to use, can be easily connected to the app and then displays all readings on the mobile device.
Thanks to the clever combination of appSensor and the accompanying free Multimeasure Mobile app, users benefit from numerous practical advantages in terms of flexibility, analysis functions, data control and documentation.
For use in stormy measurement conditions, an attachable wind shield is also included that suppresses annoying wind noise while not affecting sound level measurement.
