Overview
Product Overview
The AELAB CRY2830 Series is a family of sound level meters designed for sound and noise measurement across different monitoring requirements. Five models are available: CRY2831, CRY2834, CRY2833, CRY2833-L and CRY2833-H.
The series ranges from the basic CRY2831 non-integrating sound level meter to multifunctional models providing integrating measurement, statistical analysis, optional 1/1 octave and 1/3 octave analysis, optional monitoring functions and 32GB microSD data storage.
Selected models meet IEC 61672-1:2013 accuracy classifications. CRY2831 and CRY2834 are specified as Class 2, while CRY2833 is specified as Class 1. The supplied catalog does not state an IEC accuracy class for the CRY2833-L or CRY2833-H.
Model-dependent measurement ranges extend from the low-SPL CRY2833-L at 14～130 dB(A) to the high-SPL CRY2833-H at 44～160 dB(A), allowing selection according to the required sound-pressure-level range and measurement functions.
Key Features
