AUDAC SLM200 User manual

1. INTRODUCTION
With the SLM200 we developed a stable, safe and
reliable way to measure environmental noise levels.
This compact digital sound meter has been perfected
to achieve highly accurate measurements in a cost-
eective, tightly packed measuring instrument. We
envisioned a clever and ergonomic tool, accessible
when needed. That’s why the SLM200’s convenient
design is densely loaded with all the features of similar
bigger devices.
The SLM200 is an exceptionally versatile tool which is
convenient in a wide range of applications. Engineering,
product quality control and health monitoring are only
a handful of implementations where the SLM200 is
the appropriate tool. Applications are endless, the
SLM200 suits any environment where accurate noise
measuring is necessary.
