Full specification sheet
- Model: SLM-LP108C
- Performance Level: Grade 2 according to GB/T3785 and IEC61672
- Measured and Evaluated Quantities: LP (Time-weighted Sound Level) or Lmax (Maximum Time-weighted Sound Level), Lmin (Minimum Time-weighted Sound Level), LCpeak (C-weighted Peak Sound Level)
- Microphone: Grade 2 engineering measurement microphone, nominal diameter 12.7 mm, free-field type frequency response. Nominal sound pressure sensitivity is 50 mV/Pa (Nominal sound pressure sensitivity level is -26 dB, reference value is 1 V)
- Frequency Range: 20 Hz – 12.5 kHz
- Frequency Weighting: A-weighting, C-weighting
- Time Weighting: F (Fast response), S (Slow response)
- Measurement Range: A sound level: 30 dB – 130 dB; C sound level: 40 dB – 130 dB
- Threshold Setting Range: 30 dB – 130 dB. When the sound level exceeds the threshold, an over-threshold mark is given, and a high level is output.
- Automatic Calibration Range: ±4.5 dB (Reference value is 50 mV/Pa)
- Display: 128×64 dot-matrix liquid crystal display (LCD), resolution 0.1 dB. There are marks for overload, out-of-range, low battery voltage warning, over-threshold alarm, etc.
- Analog Output: Output jack is a 3.5 mm dual-channel headphone jack, minimum load impedance 10 kΩ.
- Analog Output: DC logarithmic voltage: The output voltage is related to the logarithm of the measured sound pressure, and the output voltage per unit sound pressure is 15 mV/dB.
- Analog Output: AC linear voltage: The output voltage is linearly related to the measured sound pressure, and the output voltage corresponding to the upper boundary of the level range is 2.0 V.
- Power Supply: 2 LR6 (No. 5) batteries. It can work continuously for 27 h under reference environmental conditions.
- Operating Temperature Range: 0°C – 40°C
- Net Weight: 0.21kg
- Gross Weight: 0.65kg
- External Size (W×D×H): 210x68x31mm
- Shipping Size (W×D×H): 250x220x70mm
