ST-109 conforms to international standard IEC61672 Class 1. ST-109 models measure SPL, Lmax, Lmin, Leq, SEL, Peak and RT60. Frequency weighting (A, C, Z) and time weighting (F, S, I) can be simultaneously surveyed. With the state-of-art microphone
technology, the dynamic range is greater than 100 dB and user doesn't need to select the measuring range prior to taking readings.
The large size LCD display shows the readings of sound level also the icons to present the current measure mode and the status of the instrument.
