The class II sound level meter is a perfect measurement device to control noise levels in places such as offices, construction sites, traffic and airports. It is equipped with an octave or third octave band filter for precise frequency analysis. The device also features a USB interface for data logging and A, B, C, and Z weightings. Time weightings allow users to choose between fast, slow, and pulse measurements. The measurement range is between 25 and 136 dB, with a frequency of 20 Hz to 12.5 kHz. The sound level meter also offers the "Peak-Hold" function to determine the peak value during a long measurement. The AD 24-bit transducer and the electronics specially developed for this device reduce self-noise to a minimum. Sampling of the measurement signal higher than 48 kHz enables high precision and good stability of the measurement value. Manufactured by PCE, with reference PCE-428
