Sound Level Meter NSLM-100 has a frequency range from 20 Hz to 12,500 Hz, covering a wide range of sound frequencies. It measures four key parameters including Lp, Leq, Lmax, and LN. This unit uses a high-quality microphone, ensuring accurate and reliable readings. It offers calibration at 94 dB at 1kHz using a sinusoidal signal for stable performance. Our sound level meter comes with a digital display, providing clear visibility of test parameters.
