Product Introduction

TesterMeter-JY228 (configuration 3) sound level meter is a digital multi-function sound level meter, designed to measure the frequency-weighted and time-weighted sound pressure level, equivalent continuous sound level, sound exposure level, statistical sound level of various noises. It has 7 working modes such as integral average, parallel measurement, statistical analysis, 24h measurement, 1/1 octave, 1/3 octave and indoor noise for users to choose. The instrument also provides optional low-frequency weighting, used for secondary noise measurement.

The TesterMeter-JY228 (configuration 3) sound level meter is a class 1 sound level meter, which complies with the national standard GB/T 3785.1-2010 and the international standard IEC 61672-1:2013 "Sound level meter", GB/T15952-2010 and IEC61252:2002 "Specifications for personal sound exposure meters", GB/T 3241-2010 and IEC 61260:2014 "Octave-band and fractional-octave-band filters". Structure-borne noise (indoor noise) meets the requirements of GB 22337-2008 " Emission Standard for community noise" and GB 12348-2008 " Emission Standard for industrial enterprises at boundary", and secondary noise meets JGJ/T 170-2009 "Standard for limit and measuring method of building vibration and secondary noise caused by urban rail transit", 24h noise monitoring meets the requirements of GB 3096-2008 "Environmental quality standard for noise" and HJ 640-2012 "Technical specifications for environmental noise monitoring – Routine monitoring for urban environmental noise", the coding of environmental monitoring points meets the requirements of HJ 661-2013 "Coding rules for monitoring point of environmental noise".

The TesterMeter-JY228 (configuration 3) sound level meter is a powerful, high-performance handheld instrument, suitable for long-term, reliable and accurate measurement of various noises. This series of products has two types of explosion-proof type and non-explosion-proof type. The explosion-proof type is divided in o intrinsically safe explosion-proof and mine intrinsically safe explosion-proof. It has an 8G SD card inside, and comes standard with AA battery power. At the same time, users can choose the power bank provided by the company to supply power according to their needs. The instrument also has functions, such as recording, timing shutdown, GPS positioning, Bluetooth, etc. It is suitable for field measurement of noise from mechanical and electrical products, environmental noise, traffic noise, industrial hygiene, and workplace noise.
