Information

Product Introduction

GHD-3000 River Guard is a set of green and clean reagent-free water quality sensor and wireless data transmission system as the core; an online monitoring system composed of modern automatic control technology, special analysis software and communication network.

 

 

The monitoring parameters of the river guard can be flexibly configured, with low cost and small size, and can be installed on the bank of the river arbitrarily. With a small amount of on-site construction, a high-density water quality sensor monitoring network can be built to meet the needs of gridding, intensive, and refined point placement. A remote monitoring system is established based on wireless local area network technology. The River Guard has the function of Internet of Things management, which can remotely view the status of the equipment, remotely control the restart, upgrade, and change of the monitoring frequency of the equipment; the system platform has data analysis, dynamic real-time evaluation, alarm locking, and graphic display; It can be matched with our water quality early warning forecasting system to realize water quality forecasting and safety early warning; it is a reliable guardian for safe management of water quality environment.

 

Features

● High integration and small size;

● Convenient deployment, movable and easy to install;

● Short construction period and small on-site construction workload

● Support power supply methods such as city power and solar energy to meet different environmental conditions

● The product has a wide range of applications, which can be applied to urban black and odorous water monitoring, water quality grid monitoring, etc.;

● The instrument and system can run stably for a long time, with little maintenance, no reagent pollution, energy saving and environmental protection;

● The overall cost of the equipment is low, and large-scale distribution can be realized;

● Continuous and accurate monitoring data, sentinel-style early warning forecast.
