Used BRUEL & KJAER / B&K 1805 #92382 for sale

BRUEL & KJAER / B&K 1805 acoustic calibrator is a high performance, single-source electrical and acoustic calibration tool used to test and calibrate sound and vibration instrumentation systems. It is designed to measure, accurately and reliably, acoustic parameters such as sound pressure level, frequency response and sound power levels of audio and audio-visual equipment. B&K 1805 consists of a low-noise, low-distortion digital oscillator, a low-noise amplifier and an optional calibrated microphone, housed in a sturdy, durable and lightweight casing. The oscillator generates a sinusoidal waveform at a precise frequency and level via the amplifier, providing a precise and steady sound pressure level (SPL) at any frequency between 100 Hz and 25 kHz, with a level variance of just ± 0.2 dB. The automotive grade, all-metal housing allows BRUEL & KJAER 1805 to withstand vigorous transportation, while it's exceptionally low distortion ensures optimal accuracy. With a calibrated microphone aligned to the unit, low-level measurements can be taken consistently and efficiently. In addition to its SPL measurement capabilities 1805 also supports a range of other acoustic test parameters. It has three switchable selectable referencing levels (110, 125 and 140 dB), switchable low-frequency and high-frequency filters and a built-in sine-waveguard, which prevents the microphone from being damaged in elevated SPL conditions. BRUEL & KJAER / B&K 1805 also offers several other key features, such as precise level setting to 1 dB accuracy, an integrated safety circuit which shuts the system down automatically and a 0 setting, allowing the user to set the reference level at any voltage up to 100 mV. Furthermore, B&K 1805 is designed to provide precise acoustic measurements in hostile environments such as sound-proof rooms and vibration-free test benches. BRUEL & KJAER 1805 calibrator is an ideal tool for audio/visual engineers and other technical professionals, as it provides an immediate, accurate and reliable calibration solution. By combining highly precise SPL measurements with a range of additional features, 1805 acoustic calibrator is the ideal choice for test and calibration applications.
