Delta Ohm HD2110L Integrating Sound Level Meter and Advanced Analyzer

HD2110L is an handheld integrating sound level meter performing either spectral or statistical analysis. The instrument is designed to deliver maximum performance in the analysis of acoustic phenomena with particular attention to regulations on environmental noise and building acoustics. Attention has been paid to the possibility to adapt the instrument’s functionsto the legislation and to meet the needs of its users. It’s possible to integrate the sound level meter atany time with options to extend the applications; the firmware can be updated directly by the user using the supplied NoiseStudio software.HD2110L meets type 1 specifications according to IEC 61672-1 2002 and IEC 61672-1 ed. 2.0 of2013 and IEC 60651, IEC 60804 standards. Compliance with IEC 61672-1 has been verified byINRIM primary metrological Institute (ref. certificate no.37035-01C).The constant percentage bandwidth filters meet the specifications of IEC 61260 Class 0 and microphone meets IEC 61094-4.HD2110L is an integrating sound level meter suitable for the following applications:

• Environmental noise levels evaluation,
• Noise monitoring with noise events capture and analysis,
• Spectral analysis in octave bands from 16Hz to 16kHz,
• Complete statistical analysis with percentile levels calculation from L1 to L99
• Measurement in working environments,
• Selection of Personal Protective Equipment (methods SNR, HML and OBM),
• Soundproofing and acoustic reclamation,
• Production quality control,
• Machine noise measurement,
• Building and architectural acoustics (with “Reverberation time” option). 

The HD2110L can be integrated with additional options to extend its application range when required; the firmware can be updated directly by the user by means of the Noise Studio program provided with the instrument.
