GNST-600JCZ type water quality automatic monitoring station
The GNST-600JCZ outdoor small-scale water quality automatic monitoring system is an online automatic monitoring system composed of online automatic analysis instruments as the core, modern sensor technology for automatic measurement, automatic control technology, computer application technology, and related specialized analysis software and communication networks. The system has the monitoring function of traditional fixed water quality automatic monitoring stations, and can select different monitoring parameters according to user needs. It can also be located at various pollution sources, sewage outlets, wetlands, lakes, and "river chief system" river sections for real-time and rapid monitoring of water quality changes, patterns, and trends, providing scientific basis for pollution discharge control, prevention decision-making, supervision, and environmental management.
