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.

With the BS30WP, you can record series measurements via logging function, compare determined data directly in the mobile device or use the measured values in combination for differentiated analysis on site.
This means that calculated maximum, minimum or average values can be conveniently displayed for the sound level measured values determined by the meter and transmitted to the app, and individual limit values can be assigned, when exceeding and falling below an acoustic alarm is automatically made.
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.

With the BS06, the sound level of various noise sources can be reliably detected within a measuring range of 40 to 130 dB(A). In addition, minimum and maximum value can be displayed.
The BS06 can also be used for quality control in construction trades, for example for detecting noise sources or too weak insulation. Often the disturbing noise is transmitted through the ventilation system or other supply shafts.
Thanks to the successful combination of innovative equipment, ergonomic design and unbeatable value for money, this precision instrument is suitable for a wide range of applications, for example for noise and noise measurement in the office, in leisure, machine checks, in private living environment, on the construction site, in the disco and much more.
For use in draughty outdoor environments, an attachable wind shield is also included that suppresses annoying wind noise while not affecting sound level measurement. An integrated sensor also permanently monitors the ambient light and automatically switches on the display lighting in low light conditions.
Advantages for practice: development, design, production: 100% Trotec, fast and reliable sound level measurements, optimal value for money, minimum value, maximum value and hold function, sensor-controlled display lighting in low light conditions, easy one-handed operation, very short response time, automatic switch-off, tripod thread, practice-optimised German industrial design, protected design

User-friendly functions: The DURFICST digital sound level meter uses a colour display to display the data. The screen features include: battery reminder, volume detection, various detection modes. The decibel meter is made of one piece with a brand new shape and the two sides are equipped with soft silicone that corresponds to the ergonomic design, so you feel comfortable when using it.
Switch between two units: Sound level meter with two new units of measurement: SONE/dB. SONE mode is widely used to detect the sound of musical instruments and the volume of performances, and comes closer to the volume of the human ear. The dB mode is used to detect ambient noise in factories and at home and has a standard decibel range.
Comfortable and lightweight: the noise level meter is lightweight at only 205 g. The product comes with a fabric bag for easy storage and transport. The DURFICST dB meter is widely used in factories, traffic, cars, baby rooms, offices with sound systems as well as in private homes, schools and on construction sites to check the sound quality.
Accurate/fast measurement: The MAX mode of the decibel meter displays the maximum/minimum values of the sound in a range, and the real-time monitoring provides you with accurate data on the sound level in a range. The dB meter also has a fast and slow response rate conversion. The fast response is suitable for general environmental measurements. The slow response is suitable for measurements in environments with relatively large fluctuations in noise level.
A/C weighted measurement method: A weighted to simulate the frequency characteristics of low intensity human ear noise, applicable for detecting ambient noise. C-weighted to simulate the frequency properties of human ear noise with high intensity, applicable for the analysis of machine motors and machine sound pressure. Sound level meter portable, more professional measurement method, offers users a more perfect experience.

With the MAX function, the last determined maximum value is displayed during the period of a measurement. For example, at a construction site you can determine how high the maximum load is within your measurement period. "Hold" fixes the last measured value for you.
The sound level meter delivers precise readings with a resolution of 0.1 dB over a wide volume range - from whispers to rock concerts. Frequencies from 32 hertz (subwoofer, church organ) up to 8 kHz (birdsong, and higher) are recorded. The accuracy is in the range of +/- 1.5 dB. A protective cap on the measuring microphone shields wind noise.
The large display makes reading the readings an easy thing even on the extended arm. In dark environments, you can turn on a display lighting.
Is the volume tolerable or already too high? What one still perceives as reasonable is no longer acceptable for the other. To find a common language here, objective readings help. This is exactly what the Brandson sound level meter delivers with high precision. When delivered, the device is already calibrated correctly. | 304418
An inch thread on the back allows a professional measuring setup using a tripod. After ten minutes of non-use, the device switches off to save the batteries (3 x AAA batteries already included).
