SoundTest-Master

Description:

– Measurement of noise levels with frequency weighting filter according to dB (A) and dB (C) standard curves as per IEC 61672 (type 2) – Selectable time weighting factors (fast 125 ms/slow 1 s) for optimum adaptation to noise dynamics – Long-term recording function with 16,000 storage points or real-time logging on PC – Selectable analogue indicator for visual assessment – Calibrated and adjusted by means of standard 94 dB/1 kHz noise level calibrator – Sensitive electret condenser microphone with detachable wind guard – Analogue outputs: DC and AC – PC software – Illuminated, transparent display
