ZHK6120 Environmental Noise Automatic Monitoring System

Main Features

Real-time monitoring of various noise parameter  indicators, supporting parallel A, C, and Z frequency  weighting, as well as Fast and Slow time weighting. 

Supports measurement of SPL, LEQ, Max, Min, Peak,  SD, SEL, and E, and supports statistical percentage  calculation (LN). 

Can be expanded to include noise exceedance triggering for octave band or third-octave band spectrum  analysis. 

Features automatic recording of noise exceedances  and an upload function. 

Supports automatic static electricity excitation  self-check. 

Built-in large-capacity lithium battery ensures the  instrument operates normally for over 24 hours after a  power outage. 

Various optional functions based on customer needs,  including traffic flow monitoring, meteorological parameter monitoring, outdoor LED display, and  GPS/BeiDou positioning. 

The data acquisition and transmission unit adopts a  standard environmental protection data logger, with  industrial-grade optical isolation for circuit input and  output interfaces, rich peripheral interfaces, and  human-machine interaction via a large-size touch  screen. 

It supports 4G and Ethernet remote data  transmission.

The online monitoring platform monitors various  parameters in real-time, with GIS maps and lists for  display; it offers massive storage and the ability to  export historical data and play back on-site audio; it  uses automatic AI recognition for determining noise  types. 

The device supports remote upgrade functions and  enables remote adjustment and setting of core user  parameters.

Application

Suitable for monitoring noise in urban  functional areas, industrial enterprise boundaries, traffic noise, construction site boundaries,  social life noise monitoring, and other environmental noise research scenarios.
