ST-105S Class 1 Integrating Sound Analyzer Meter
The ST-105S Class 1 Integrating Sound Analyser Meter is an advanced, portable sound analyser capable of measuring A, C and Z as well as F, S and Impulse. It is highly accurate and conforms to IEC 61672 Class 1 accuracy standard. The dual functionality of the device allow it to both take measurements and instantly produce statistical analyses in the 1/1 and 1/3 octave bands which saves time and space by negating the need to transfer data to a separate analysis device. This also makes it perfect for measuring and analysing background noise in the workplace, product noise and environmental noise. The ST-105S has a 24 hour automatic measuring function with adjustable intervals for ease of use.
