Jiaxing Hengsheng HS5661C Noise Spectrum Analyzer

The HS5661C noise spectrum analyzer is a pocket sized intelligent noise measurement instrument that integrates a precision sound level meter and a spectrum analyzer. Its performance meets the requirements of GB/T3785 and IEC61672-2002 level 1, as well as the requirements of IEC61260 and GB/T3241 for 1/1 octave band filters and 1/3 octave band filters. It is suitable for noise measurement in various industrial environments, especially for noise spectrum analysis.

• technical parameter

1 Microphone: Ø 12.7mm (1/2 ") Test condenser microphone

2 Frequency range: 10Hz~20kHz

3 Frequency weighting: A weighting, C weighting, Lin (linear)

Measurement range: 25dB~130dB (A)

5-scale control: manual, divided into three levels, linear range>60dB.

6 Range: 25dB – 90dB 50dB – 110dB 70dB – 130dB

The above range is the value at the factory. When the user adjusts the calibration value or replaces the microphone, the range may change. The specific range is determined by the overload indication and lower limit indication when the range is high or medium; When the measurement range is low, the upper limit is determined by the overload indication, and the lower limit is determined by the background noise.

7 Instrument Accuracy: Compliant with IEC61672 standard, Level 1

8 time weighting: fast (F), slow (S)

9 Filters: Built in 1/1 and 1/3 octave band filters.

10 Display: Large screen dynamic LCD display, instantaneous sound level, with analog meter display.

11 output interfaces: AC output, RS-232 interface

12 Calibration: Use a Type 1 sound level calibrator or piston sounder.

13 Power supply: Internally equipped with LR6 (5 #) alkaline battery, capable of continuous operation for 24 hours. External power supply 6V.

14 Dimensions: l × b × h (mm): 230x72x30

15 Quality: 300g (with battery)

16 Usage conditions: -10 ℃~50 ℃
