HT-80A Sound Level Meter
Industrial-production noise, construction noise, transportation noise, and everyday social noise expose many people to noise pollution. Better prevention and control of noise pollution are essential issues for social governance. The HT-80A digital sound-level meter provides noise monitoring from multiple perspectives. A condenser-microphone high-definition sensor offers more precise noise measurement and stable results each time. Alarm thresholds can be set as desired, with an automatic alarm when the limit is exceeded.
