Noise assessments are easier when one portable instrument covers routine measurements today and can be upgraded for tomorrow’s tasks. HD2010UC is an integrating sound level meter for env noise, workplace exposure, machine noise and production quality control, with Class 1 (HD2010UC.kit1) or Class 2 (HD2010UC.kit2) versions according to IEC 61672-1:2013.
Three parameters with freely selectable frequency weightings and time constants, including Leq, SEL, Lmax, Lmin, Lpk, Dose and Ln. Integration times from 1 s to 99 h and the Back-Erase function help manage unwanted events, while statistical analysis displays up to three percentile levels between L1 and L99.
For more demanding campaigns, the HD2010.O2 Advanced Data Logger option adds time history profiles, reports, event capture and full statistics from L1 to L99. RS232 and USB interfaces, Noise Studio software, acoustic or electrical calibration and optional SD-card storage up to 2 GB support efficient field work and later reporting.
HD2010UC conforms to IEC 61672-1 of 2002 and IEC 61672-1 ed. 2.0 of 2013, IEC 60651 and IEC 60804 specifications with class 1 (HD2010UC.kit1) or class 2 (HD2010UC.kit2) tolerances.
It has been designed combining price competitiveness and simplicity of use. Attention has been paid to the possibility of updating the instrument, and the HD2010UC can be integrated, at any time, with other options like “Advanced Data Logger” to extend its application scope.The meter measures programmable acoustic parameters with integration times from 1 s to 99 h.
Basic version Internal memory allows storage of more than 500 records; HD2010.O2 "advanced datalogger" option adds 3 x SLM selectable parameters @0.5s, 1 x profile parameter @125ms , 5 x broad-band report parameters @1s to 1h logging period parallel recording. In addition sound event capture, markers, delayed start and full percentile analysis. Optionally, for long term measurements, the 8MB internal flash memory can be extended with HD2010MC SD card reader for storage up to 2 GB (HD2010.O2 required).
As a statistical analyzer (option HD2010.O2 “Advanced Data Logger”) the HD2010UC samples the sound signal 8 times per second with. A-frequency weighting and FAST time constant, and analyzes it statistically in 0.5 dB classes. It is possible to display up to 3 customer selecatble percentile levels between L1 and L99. With “Advanced Data Logger” option it is possible to choose whether sampling LFp, Leq o Lpk with A, C or Z weightings (only C and Z for Lpk).
Acoustic parameters: Spl, Leq, LeqI, SEL, LEP,d, Lmax, Lmin, Lpk, Dose, Ln
Frequency weightings Simultaneous: A, C, Z (only C and Z for Lpk)
Time weighting Simultaneous: FAST, SLOW, IMPULSE, Peak
The instrument provides RS232, USB, AC LINE output, DC output and external power supply input.
Calibration can be performed with an acoustic calibrator or the built-in reference generator with electric calibration.
Noise Studio 1.0 Basic software (included FOC) supports data download, graphical and tabular display, data export, printing, PC setup and firmware updates.
Optional software add-ons are available for dedicated acoustic analysis applications.
