Detail Laserliner SoundTest-Master
SoundTest-Master
– Measurement of noise levels with frequency
weighting filter according to dB (A) and dB (C)
standard curves.
– Selectable time weighting factors (fast 125 ms/
slow 1 s) for optimum adaptation to noise dynamics
– Long-term recording function with 16000 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, clearly arranged display
