This precision noise level measuring instrument uses frequency weighting filters according to dB (A) and dB (C) standard curves. A choice of two time weighting factors (fast/slow) allows optimum adaptation to noise dynamics The selectable analogue indicator provides a visual assessment of the test area. The measurement is taken with a long-term recording function with 16,000 storage points or real-time logging on a PC using the supplied software. The device has analogue DC and AC outputs and an illuminated display. Calibration and adjustment is by means of a standard 94 dB/1 kHz noise level calibrator. Supplied with USB cable, batteries and carrying case.
