Sound level meter - HD2010UC

HD2010UC is a portable sound level meter able to perform statistical analysis. The instrument has been designed combining economy and simplicity of use.

Attention has been given to the possibility to update the instrument and is possible to integrate options that can extend applications included. Firmware can be updated directly from user, using “Noise Studio” supplied

Applications :

  • Evaluation of environmental noise level;
  • “Data logging” optionally;
  • Capture and analysis of acoustic events, optionally;
  • Statistical analysis with calculation of three percentile
  • levels or complete statistical analysis (optionally);
  • Identification of impulsive noises;
  • Measures in workplaces;
  • Choice of self-protection equipment (SNR and HML methods);
  • Production quality control; Measure of machinery noise.

According to : IEC 61672-1, 2002 (Certificate of Conformity I.N.RI.M n.07-0124-02), IEC 60651 and IEC 60804.
