    1 Introduction

    The CEL-63x series is a family of noise meters (where „x‟ is a digit that indicates

    the model variant – see Figure 14 on page 54). These are powerful

    measurement tools to support a wide range of industrial, health and safety, and

    environmental noise measurement requirements.

    For a breakdown of the different models and their functionality, refer to

    section 5 “Specifications” beginning on page 54.

    The CEL-63x instrument uses the latest digital signal processing technology to

    provide a full range of functions, including integrating and real-time octave and

    1/3-octave band analysis.
