INTRODUCTION

MEWOI-JY218B Integral Average Sound Level Meter is a hand-held instrument. Its performance meets the requirements of Class 2 X Time Average Sound Level Meter and Integral Sound Level Meter in National Standard GB/T 3785-2010 and International Standard IEC 61672:2013. This sound level meter is the latest all-digital sound level meter launched by the company. It is light and portable. It is suitable for on-site measurement of noise of mechanical and electrical products, environmental noise, traffic noise, workplace noise and so on. It can also be used for teaching demonstration in Colleges and universities.

MEWOI-JY218B integral average sound level meter is an improved product of MEWOI-JY208C sound level meter. It has the function of manual integral average. It is mainly used to measure time weighted sound level, sound exposure level, cumulative percentage sound level, sound exposure and noise dose of various kinds of noise. MEWOI-JY218B Sound Level Meter uses internal memory to save only one integral measurement result, without loss of power. After each measurement, it automatically covers the last result and saves it. It can also print the measurement result on the spot.
