Model # MSL 1

The SPL Meter PCE-MSL 1 is a simple sound measuring device. The SPL meter PCE-MSL 1 is used to quickly determine the ambient volume. In addition to the volume measurement, the decibel meter also has the facility to determine the ambient temperature.
The measurement of background noise is important in almost every situation today. For this purpose it is helpful to use a simple decibel meter that gives the user an initial idea about the possible noise level.
The LC display gives clear results of the measurements made by the sound level meter. A backlight is also integrated into the display. The sound level meter is especially ideal for measurements that need to be non-stationary.
