HD2010UC is an integrating portable sound level meter performing statistical analysis. The instrument has been designed combining maximum low cost and simplicity of use. Attention has been paid to the possibility of adjusting the instrument and adding options at any time to the HD2010UC so to extend its applications. The user can upgrade the firmware directly by means of the Noise
Studio programme supplied with the instrument. HD2010UC is equipped with a backlit graphic display. HD2110L is an integrating sound level meter suitable for the following applications:
•Environmental noise levels evaluation,
•noise monitoring with noise events capture and analysis,
•Statistical analysis with calculation of 3 percentile level and optional full statistical analysis
•measurement in working environments,
•selection of Personal Protective Equipment (methods SNR, HML and OBM),
•production quality control,
•machine noise measurement,
•Measurement of machine noise, sound power measurements
•Optional Advanced Data Logging
•Optional capture and analysis of sound events

With HD2010UC sound level meter it is possible to measure the sound pressure level by programming 3 parameters with the possibility of freely selecting the frequency weightings and time constants. It is possible to measure parameters such as Leq, SEL, maximum and minimum sound levels with integration times from 1 second to 99 hours. If an undesired sound event produces an over-load indication, or simply alters the result of integration, it is always possible to exclude the event by using the Back-Erase function.
The measured sound levels can be saved and transferred to a PC with Noise Studio Software

With the addition of the optional Advanced Data Logger module the HD2010UC can sample the sound signal 8 times per second with a frequency weighting and FAST time constant and analyzes the the signal statistically in 0.5 dB classes. Three percentile levels between L1 and L99 can be displayed. You can select sampling LFp Leq or Lpk with A, C or Z weightings (only C and Z for Lpk)

Data can be transfered to a PC or a printer. The bidirectional serial interface can by used to control the instrument from a PC
