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:
ORDERING CODES:
HD2110L.Kit1: includes, HD2110L sound level meter, MC21E prepolarized ½” condenser microphone (alternatively MC21P or MC22Pmicrophone polarized at 200 V) and HDSAV windscreen, HD2110PELpreamplifier (HD2110PL in combination with the microphonepolarized at 200 V MC21P or MC22P), HD2110USB cable (alternatively,on request, HD2110RS serial cable for RS232 connection), NoiseStudio software and carrying case, individual ISO17025 calibrationcertificate, according to IEC 61672, of the chain consisting of soundlevel meter, preamplifier and microphone. ISO17025 calibrationcertificate, according to IEC 61260, of the octave filters bank.
HD2110.O1: option “Third octave”: spectral analysis with double bank ofthird octave from 16 Hz to 20 kHz and from 14 Hz to 18 kHz accordingto IEC 61260. Evaluation of audibility of the spectral componentsby real-time comparison with the isophonic curves ISO 226:2003.ISO17025 Calibration certificate according to IEC 61260 of the bankfrom 20 Hz to 20 KHz included.
HD2110.O4: option “Reverberation Time”: reverberation timemeasurement both with steady source interruption and withimpulsive noise back integration method (Shroeder’s) according toISO 3382. Reverberation time measurement performed in octavebands from 125 Hz to 8 kHz, and third octave bands (option HD2110.O1) from 100 Hz to 10 kHz with sampling interval 1/32 s. Automaticcalculation of reverberation times EDT, T10, T20 and T30 on allbands, and decay profile analysis with the possibility to calculate thereverberation time over a chosen interval.
HD2110.O6: option “FFT” - constant bandwidth FFT analysis. This optionadds: Leq profile at 1/32 s intervals. Narrow band spectrum analysis (FFT)from 7Hz up to 22KHz with spectral resolution from 1.5Hz to 100Hz.
HD2110.O1/4: option “Microphone set for measurements up to 160dB”.- Microphone chain with ¼" microphone
HD2110.O1/4H: option “Microphone set for measurements up to180dB”.- Microphone chain with ¼" microphone
HD2110.OE: option “Microphone protection for outdoor measurements”replacement of the standard HD2110PEL preamplifier with the heatedversion HD2110PEWL. The heated preamplifier can be combined withHDWME outdoor microphone protection and is equipped with CTCdevice for electrical calibration and integrated 5m extension cable (otherlengths 10m, 20m and 50m on request).
HD2011.OMN: option “Monitor”: extension of datalogger functions forcombined use with HD2011NMT station.
