The precision sound meter Laserliner SoundTest-Master uses frequency-weighted filters according to standard dB(A) and dB(C) curves. It features a selection of two time weighting factors, fast and slow, for optimal adaptation to noise dynamics. The analog display offers a visual assessment of the test area with the possibility of long-term recording of 16,000 points or real-time logging on a computer via the supplied software. The instrument has analog DC and AC outputs, as well as an illuminated display.
