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.
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.
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.
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.
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.
SL400 Sound Level Meter
Professional Class 2 Phonometer with data logger function and calibration certificate according to ISO
Whether occupational safety, health prophylaxis, quality control or noise protection testing – with factory ISO calibration, integrated live logging function and included analysis software, the universal sound level meter SL400 is ideal for professional control and monitoring of workplace, industrial or environmental noise.

Many functions - large box contents
The SL400 is also equipped with a live logging function and has a data storage for recording up to 32,700 readings. The determined data can be easily transferred to a PC via USB for software-based analysis.
The included software enables a live recording of the measured values with real-time display, a graphical or table display of the measured values with expression option as X-Y chart or tabular, as well as a zoom function and export possibility in Excel format.
For logging or continuous measurement inserts, the SL400 can also be attached to the included mini tripod. With time-consuming long-term measurements via the included power supply, you can easily switch from battery to mains operation via the integrated power supply.
In addition, a 3.5 mm jack socket integrated to the SL400 offers connection options for frequency analyzers or X-Y writers.
An ISO calibration certificate is already included with the SL400.
Last but not least, the SL400 impresses with its handy format with low weight and the button layout optimised for one-handed operation – the ideal basic equipment for sound level measurements in the fields of industry, work and environmental protection.
Sound level meter for noise measurement and quality control in e.g. offices, factories, schools or on busy roads. Complies with Class 2 accuracy.
