Description
Overview
GAOTek Sound Level Meter measures Lp, Leq, Le, Lmax, Lmin and Lx and features a 4 digit display with 0.1 dB resolution with backlighting and an analog bar graph. Use it to monitor noise exposure and environmental noise while out in the field. Its lightweight and compact design makes it easy to travel with.
