Steinberg Systems Støymåler - 30 to 130 dB 10030412

Everyone reacts differently to noise, however with the sound meter you can determine exactly how loud it is in your office, workshop or on the street. The sound meter registers human-caused sounds as well as noise produced by machines. It can be set for exact measurement results in a variety of conditions and meets general standards. With a measurement range of 30 to 130 dB, the sound level meter was developed to meet the technical standards of IEC 61672: Type 2. It enables you to draw reliable conclusions about a variety of sound sources, as well as precisely measuring, recording and analysing them. The sound pressure level meter stands out with a measurement accuracy of ± 1.4 dB, which makes possible an exact classification of the collected data, whether it is for street noise or for sounds produced by machines. In order to ensure precision, you can preselect one of three measuring ranges: light (30 - 80 dB), medium (50 - 100 dB) and high (80 - 130 dB). If you aren't sure which range is the right one, you can use the automatic range to cover the entire measuring range. The sound meter effectively recognises a frequency range of 31.5 Hz to 8 kHz, meaning it can also measure frequencies that are not audible to the human ear. The meter has selectable frequency weightings for optimum measurement results: Frequency weighting A is ideal for ambient noises in for example an office, while in frequency weighting C the device registers sound sources originating from machines. The Fast and Slow functions enable you to better measure and describe the dynamic of the recorded sound sources. In Fast mode, the device measures with a speed of 125 milliseconds, thereby recording rapid changes in sound pressure better than in Slow mode, in which measurements are taken every second to show a more continuous sound level. All of these settings can be easily selected using just a few buttons. The collected data is shown on the four-digit LCD display to within one decimal point so you can check it immediately. The collected data can also be saved and transferred to a computer via a USB connection for further analysis. The sound meter is powered by a 9 V battery and has a maximum operating time of 30 hours per fully-charged battery. It has enough memory for up to 262,100 measurements. The microphone is equipped with a windscreen for optimum results, even outdoors. The three-footed tripod where you can securely place the device is a practical accessory, especially for taking longer measurements. ...
