Brunel & Kjaer Investigator 2260 Noise Analyzer

Description: Slightly used in great working condition. One of the battery contact tabs is corroded but it has been cleaned. It comes with the analyzer, the carrying case and the carrying strap only as shown in the pictures. Ready to ship. Thank you. Linear Operating Range: 80dB adjustable to give full-scale readings from 80dB to 130dB in 10dB steps Max. Peak Level: 3dB above full scale reading OCTAVE AND 1/3-OCTAVE BAND FILTERS Octave Band Centre Frequencies: 8Hz to 16kHz 1/3-octave Band Centre Frequencies: 6.3Hz to 20kHz DETECTORS Parallel detectors on every measurement: A-weighted broad-band detector channel with three exponential time weightings (Fast, Slow, Impulse), one linearly averaging detector and one peak detector C- or L-weighted (switchable) as above for A-weighted Octave and 1/3-octave band filters, pre-weighted either A-, C- or L-, each with a detector channel containing one linearly averaging detector and one exponentially averaging detector switchable between Slow or Fast Overload detector which monitors the overload outputs of all the frequency weighted channels INHERENT NOISE LEVEL (Combination of electrical noise and microphone thermal noise at 20°C). Typical values with supplied microphone of nominal sensitivity: Weighting “A” “C” Lin. 5Hz–20kHz Electrical Noise (2260) 12.3dB 14.0dB 19.2dB Thermal Noise (4189) 14.6dB 15.3dB 15.3dB Combined Noise 16.6dB 17.7dB 20.7dB Lin. 3Hz–20kHz CORRECTION FILTERS Upper Limit (RMS) for Crest Factor=10: 17dB below full scale reading 26.4dB 15.3dB 26.7dB Sound Incidence: Built-in filters for correction of frontal/random sound incidence Passive Attenuation: Microphone attenuator ZF0023 (included) effectively increases all full-scale readings by 20dB Windscreens: Built-in filters for correcting the influence of Protective Cover UA1236, and Windscreens UA0459 and UA0237
