ST-106 Class 1 Integrating Sound Level Meter
IEC-61672-1:2013 class 1
Application
ST-106 is a high performance conforms to international IEC61672-1:2013 Class 1 Integrating Sound Level Meter. It may also survey: Lxyi, Lxyp, Lxeq, Lxmax, Lxmin, LAE, Lcpeak, Lzpeak, three kind of at the same time frequency weighting (A, C, Z) and three kind of at the same time weighting (F, S, I) may simultaneously survey many kinds of appraisal target, the dynamic range is bigger than 110dB, it does not need to select the measuring range when doing measurements, the operation is simple.Applications: Evaluation of environmental noise, Measurements of noise at workplaces, Assessment of product noise.
