Features

ST-107S is a high performance conforms to international IEC61672-1:2002Class 2 
Integrating Sound Level Meter. It may also survey: SPL(Lxyp), Lxmax,Lxmin,,Lxeq, SEL (LAE)，Lcpeak, RT60, 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 100dB, it does not need to select the measuring range when doing measurements, the operation is simple.
