NDL 10 is a high-quality noise dose meter or sound level meter with data logging capabilities. This noise dosimeter records sound pressure level (SPL) measurements as well as dosimetry (dose) measurements in decibels (dB) and saves the measurement data to the internal memory or an SD card (SD card included).

 

Note: To set up the SD card for the first time, the NDL 10 must be connected to AC power adapter (AC power supply NET-LUT or NET-LUT-US sold separately - see accessories tab).
