Integrating sound level meter - HD2010UC/A

Portable analyzer HD2010UC/A is an integrating sound level meter with data logging functions able to perform spectrum and statistical analysis. This instrument is designed to combine maximum flexibility of use , economy and simplicity of use. Attention has been given to the possibility to adapt the instrument to the evolution of noise regulations and to the needs to satisfy today’s and tomorrow user requests.

Is possible to integrate in every moment HD2010UC/A with options able to extend applications, the firmware can be updated directly by user using Noise Studio software equipped.

Octave and third octave filters class 1 according to IEC61260

Applications :

  • Evaluation of environmental noise levels;
  • Monitoring of noise and optionally capture of acoustic events;
  • Spectrum analysis for octave bands and optionally for third octave from 25 Hz to 12,5 KHz;
  • Statistical analysis with calculation of 3 percentile levels and optionally complete statistical analysis;
  • Identification of impulsive noises;
  • Measures in work places;
  • Choice of self-protection equipment ( methods SNR , HML and OBM );
  • Sound insulation and reclamation;
  • Quality control of production;
  • Machinery noise measurement;
  • Architectonical acoustic and buildings measure (optionally).
