Sound Level Meter Specification:
| 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. |
| 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. | |
| 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 |
