Data acquisition instrument

The data acquisition instrument is also called data acquisition instrument and data acquisition and transmission instrument. The data acquisition instrument is an automatic environmental monitoring data acquisition instrument that integrates data collection, processing and transmission. It is mainly used in the field end of the environmental online monitoring system. It mainly realizes collection, Store data from various types of monitoring instruments.

With its high-speed computing capabilities, massive data storage, flexible networking methods, and convenient human-computer interaction, the data acquisition instrument is widely used in pollution source monitoring, surface water monitoring, air quality monitoring, regional environmental noise monitoring, atmospheric environmental pollution sources, Monitoring fields such as surface water pollution sources, underground water pollution sources, marine environmental pollution sources, soil environment monitoring, radioactive environmental pollution sources, etc.
The data collector is installed at the wastewater and exhaust gas discharge outlet of the pollution source (or other environmental monitoring points, such as noise monitoring points, VOC monitoring points, etc.), and collects flow meters, chemical oxygen demand (COD) monitors and flue gas continuous emission monitoring systems in real time (CEMS) and other monitoring equipment, the data is transmitted to the Environmental Protection Agency server through wireless network (GRPS/3G/4G, etc.) or wired network. Managers can view data, conduct statistical analysis and other operations by accessing the monitoring system software installed on the Environmental Protection Bureau's server.
