Introduction: The HY108C-2 sound level meter is a hand-held instrument whose performance meets the requirements of the national standard GB/T 3785-2010 and the international standard IEC 61672:2013 "Sound Level Meter" for Class 2 Class X sound level meters. This sound level meter is the company's latest all-digital sound level meter. It is also a simple sound level meter. It is lightweight and easy to carry. It is suitable for on-site measurement of noise from electromechanical products, environmental noise, traffic noise, and workplace noise. It can also be applied to teaching demonstration in colleges and universities. The signal output of this sound level meter is only analog DC output. Technical Parameters: Performance level: GB/T3785.1-2010 and IEC61672-1:2013 level 2. Measured evaluation quantity: LP (time-weighted sound level) or Lmax (maximum time-weighted sound level). Microphone: HY205 type 2 engineering measurement microphone, nominal diameter 12.7 mm, free-field frequency response. The nominal sound pressure sensitivity is 30 mV/Pa (the nominal sound pressure sensitivity level is -30.5 dB, and the reference value is 1 V). Frequency range: 20 Hz～10 kHz. Frequency weighting: A weighting. Time weighting: F (fast response), S (slow response). Measuring range: 30 dB～130 dB. Automatic calibration range: ±3.5dB (reference value is 30mV/Pa). Display: 128×64 dot-matrix liquid crystal display (LCD), resolution 0.1dB, with signs such as overload, underrange, low battery voltage alarm, and over-threshold alarm. Analog DC output: The output jack is a 3.5 mm dual-channel headphone jack, and the minimum load impedance is 10kΩ. ——DC logarithmic voltage: The output voltage is related to the logarithm of the measured sound pressure, and the unit sound pressure output voltage is 15 mV/dB. Power supply: 2 LR6 type (No. 5) batteries, can work continuously for 27h under reference environmental conditions. Dimensions: length × width × thickness 210 mm × 68 mm × 31 mm. Weight: 210g. Operating temperature range: 0℃～40℃.
