Laserliner Sound Test Meter
Noise level measuring instrument with integrated long-term storage
– 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
