PCE-NDL 10 is a high-quality sound level meter with data logging capabilities. This noise dosemeter 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 (included).

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