Class 1 Integrating   Sound  Analyzer    Level Meter

Class 1 comply with IEC – 61672-1: 2013 Class 1  
                                 IEC – 61260-1995 Class 1

Application

The Sound Analyzer Meter is a hand held real-time analyzer that can perform integrated measurement and statistic analysis on the noise (refer to paragraph 4), or other electrical signal including their frequency spectrum and amplitude 1/1 OTC and 1/3 OTC (refer to paragraph 5) value through the digital signal processing technology. 
This analyzer can be widely used in the various fields such as environmental protection, labor hygiene, research and teaching, industrial enterprise, measuring and testing etc. It can perform the environmental noise measurement, machine’s noise analysis, sound power level measurement, building acoustics measurement.
