The HD2010 is a precision integrating portable sound level meter, with data logging
functions, performing both spectrum and statistical analysis. The instrument has been designed combining maximum flexibility and simplicity. Attention has been paid to the possibility of adjusting the instrument to regulatory modifi cations and to the necessity of meeting its users’ needs of today and tomorrow. The HD2010 can be integrated with other options to extend its application scope at any time; the firmware can be directly updated by the user by means of the DeltaLog5 program ( supplied with the instrument) .
