PCE LEQ Sound Level Meter PCE-354

The LEQ sound level meter is a small handheld device with many functions such as peak measurement, Leq value calculation and adjustable measuring ranges. In addition, the LEQ sound level meter can freeze the largest measured value with the MAX function so that you can really judge whether a limit value has been exceeded. The special feature of the LEQ sound level meter is the Leq value which, after entering a time, displays the equivalent continuous sound level, i.e. the time average of all sound events within an observation period.

The memory function offers 99 locations that can only be called up via the LEQ sound level meter. The backlit display makes it easy to read, and the LEQ sound level meter switches off automatically after 10 minutes of inactivity.
A battery symbol shows you in good time when the three AAA batteries need to be replaced. The LEQ class 2 sound level meter is used in the workplace, e.g. for noise protection of employees or simply for quick measurement of ambient noise.
