1. Voltcraft Sl-451
Digital sound level meter according to EN 61672-1 Class 2 with nearly unbeatable features. In addition to the usual standard functions, the SL-451 includes a data logger and a USB interface. Its robust housing with a rubber protective frame makes the device suitable for tough use. It has a measurement range of 30 to 130 dB with an auto-range function. An integrated data logger allows for the storage of up to 32,000 measurement values, which can later be read and processed on a PC using the supplied software. This makes long-term monitoring easily achievable. With the detachable microphone and the included 3 m extension cable, measurements can also be taken in hard-to-reach locations. The SL-451 software enables measurements and evaluations according to DIN 15905-5 to prevent hearing damage from high sound emissions of electroacoustic sound systems.

2. Voltcraft Schallpegel-Messgerät SL-10 R
The housing of the Voltcraft SL-10 R sound level meter is made from 85% recycled granulate. Additionally, conventional epoxy composite material is avoided as a carrier for the internal electronics board, opting instead for ceramic as the substrate. Technically, the SL-10 R corresponds to the previous SL-10 and allows for quick and easy sound level measurements with linear frequency weighting (dBA) using the preset parameters. It is ideal for simple measurement of environmental noise or other sound sources. Furthermore, the meter features two different measurement intervals (Fast/Slow) for various applications. The color of the housing may vary slightly due to the recycled granulate.

3. Unit Uni-T
Sound level meter UNI-T UT353 mini. The UT353 is a reliable and easy-to-use sound level meter that allows you to take accurate measurements of ambient noise. With this versatile device, you can measure sound levels from 30 dB to 130 dB. Ambient sounds are converted into electrical signals, and the device displays the results on its LCD screen. Additionally, with the data storage function, you can freeze the measurements on the screen for easy reading, while the LCD backlight facilitates measurements in low light conditions. Other valuable features include a MAX/MIN mode, a low battery and overload indicator, and an automatic shut-off function.

4. PCE Instruments PCE-324
The sound level meter offers a wide measurement range of 30 to 130 dB (dBA) and 35 to 130 dB (dBC), making it suitable for accurate measurements in various acoustic environments. The accuracy of the device is ±1.5 dB at 94 dB @ 1 kHz. Equipped with A and C frequency weighting as well as both fast and slow time weighting, the sound level meter is versatile and adaptable to different requirements. The 2-inch LC colour display provides a clear and easy-to-read presentation of the measured values in numerical form. In addition, the device has a scale that enables a quick visual assessment of the sound level. With a measuring rate of 2 x per second, the sound level meter records acoustic changes almost in real time and is therefore particularly suitable for monitoring sound levels in dynamic environments. The sound level meter is equipped with functions such as MIN, MAX and HOLD. Thanks to the automatic switch-off function, the device is energy-efficient and saves battery power, which extends the operating time. The sound level meter complies with IEC 61672-1 (Class II). It is powered by 4 AAA batteries and is therefore mobile and flexible in use. Whether in residential areas, offices, production facilities or other environments - this sound level meter is versatile and delivers precise results in a wide variety of acoustic scenarios.

5. PCE Instruments Schallpegelmesser
Class II sound level meter with data logger, USB interface, measurement range of 30 - 130 dB, LC display, including software, memory for up to 32,700 measurement values. The sound data logger PCE-322A is particularly suitable for measuring noise pollution in the fields of industrial, health, safety, and environmental monitoring. The data logger features a logging function that allows for the storage of up to 32,700 measurement values, making it ideal for long-term monitoring. The PCE-322A data logger can be connected to a PC via a USB cable. Live measurement is also possible with the sound level meter, and the data can be viewed directly and analyzed. The software provides data representations in graphic formats and tables. This data can be transferred to Microsoft Excel, for example. The sound level meter has an analog output and offers additional features that are unique in its class.
