HS5660C Precision Noise Spectrum Analyzer
|
1、 Overview The HS5660C precision noise spectrum analyzer is an intelligent noise measurement instrument that meets the requirements of IEC61672 standard for level 1 sound level meters and GB3785 standard for type 1 sound level meters, as well as the requirements of IEC6260 and GB/T3241 standards for octave band filters. The analyzer adopts digital detection technology, which greatly improves stability and reliability, and is suitable for noise measurement in various industrial environments, especially for frequency spectrum analysis of noise. This instrument is convenient and reliable for measuring various noises, and can be widely used in environmental monitoring, health and epidemic prevention, labor protection, school teaching, scientific research and other departments. 2、 Main technical parameters and performance 1 Microphone: Ø 12.7mm (1/2 ") pre polarized test condenser microphone 2 frequency range: 10Hz-20kHz 3 Frequency weighting: A weighting, C weighting, Lin (linear) 4 Measurement range: 25dB-130dB (A), 30dB-130dB (C), 40dB-130dB (Lin) 5-scale control: manual selection, divided into three levels, linear range of 70dB. 6 Range: L: 23dB -90dB M：40dB -110dB H：70dB -130dB 7 Instrument Accuracy: Complies with IEC61672 Level 1 or GB3785 Type 1 8 time weighting: fast (F), slow (S) 9 timed measurements: Lp, Leq, Lae, L5, L10, L50, L90, L95 Lmax, Lmin, SD, Ld, Ln, Ldn, etc 10 time settings: 10s, 1min, 5min, 10min, 15min, 20min 1h, 4h, 8h, and 24-hour duration. 11 Sampling time: 31ms 12 Filter: Built in 1/1 octave band Center frequencies: 31.5Hz, 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz.
