The data logging sound level meter is used to determine volume. The PCE-NDL 10 data logging sound level meter is a handy measuring device that meets the highest requirements. In order to evaluate the measured data in the best possible way, it is possible to use the internal measurement data memory on the noise dosimeter. In addition, the data logging sound level meter has an SD card slot that enables the use of an SD card as an additional storage medium.

• Measuring range: SPL: Auto 30 … 130 dB
• Resolution: 0.1 dB
• Low sampling rate
• Automatic or manual storage
• Selectable storage interval
• Backlit LC display
• Dose measurement or SPL measurement
