Description
Overview
GAOTek sound decibel level tester is two overlapping measurement ranges : 60 – 130 & 70 – 140dB, A & C RMS weightings, Linear & C Peak weightings, Fast & Slow time weightings, and energy exchange rates (Q) of 3, 4, 5 & 6. In dose measurement mode, it display % dose, % dose projected for an 8 hour period, peak level and measurement duration. For countries that are subject to European Union regulations or the equivalent ISO standards The meter is able to measure and save up to five specified Ln values.
