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.
