Description

PCE Instruments Data-Logging Decibel Meter (PCE-NDL 10) is a high-quality noise dosimeter designed to measure sound pressure levels (SPL) and dosimetry (dose) in decibels (dB). It records measurements and saves the data to internal memory, which can be transferred to an SD card for convenient data management.

Equipped with manual and adjustable automatic data logging, the device offers features such as data hold, min/max values, date/time stamping, auto shutdown, and an audible alarm. The backlit LCD screen ensures clear visibility, and the meter’s portability makes it suitable for various applications.
