Introduction
Thank you for purchasing a PCE-353 sound level indicator from PCE Instruments.
With this sound level indicator, you are able to measure the sound exposure level (SEL), as well as the
equivalent continuous sound level (L
eq)
, which is commonly used for industrial noise measurements. This
enables you to determine the noise pollution at workplaces. You can also set alarm thresholds, which
trigger an alarm signal when certain sound levels are exceeded.
The measured data can be transferred to a PC via the RS-232 interface.
