Introduction: The HY126C sound level meter is a hand-held instrument whose performance complies with the requirements of the national standard GB/T 3785-2010 and the international standard IEC 61672:2013 "Sound Level Meter" for the Class 2 X-class integral sound level meter. GB/T 15952-2010/IEC 61252:2002 "Personal Acoustic Exposure Meter Specification", which is applicable to on-site measurement of mechanical and electrical products noise, environmental noise, traffic noise, industrial hygiene and workplace noise. The HY126C Sound Level Meter is a digital multi-function sound level meter with two modes: integral averaging and statistical analysis. It is designed to measure the time weighted sound level, time average sound level, sound exposure level, and accumulation of various noises. A variety of acoustic evaluations such as percent sound level, acoustic exposure and noise dose. Technical Parameters: 1. Performance level: GB/T3785 and IEC61672 Level 2. 2.
