OC-HY128 Class 1 Digital Sound Level Meter, 30-130dB professional decibel meter with 24h continuous noise monitoring, octave band analysis optional, for workplace, industrial and environmental noise testing.
Product Description
OC-HY128 multi-function sound level meter is a fully digital Class 1 noise meter, engineered for accurate acoustic evaluation across industrial and environmental noise measurement scenarios. It measures frequency-weighted & time-weighted sound pressure level, equivalent continuous sound level, exposure sound level and statistical sound level.
7 optional working modes are integrated: integral average, parallel measurement, statistical analysis, 24h continuous measurement, 1/1 octave, 1/3 octave and indoor noise test. It supports low-frequency A-frequency weighting, perfectly suitable for secondary radiation noise measurement.
This decibel meter works while charging via power bank, meeting long-duration field monitoring demands. Recording and Bluetooth data transmission functions are available as optional upgrades. The optional octave and 1/3 octave band analyzer enables advanced spectrum analysis for professional noise research.
Ideal for workplace noise testing, environmental noise inspection, factory noise assessment, indoor noise evaluation and occupational noise exposure monitoring.
