Recently, the relevant environmental management units in Kangle County, Gansu Province have purchased a complete set of water quality, hydrological and rainfall monitoring system equipment from our company to provide real-time online monitoring of local hydrological, water quality and rainfall conditions. After safely transporting the entire set of equipment to Kangle County, our company assisted the unit in counting the quantity and inspecting the quality of the equipment. We also smoothly assisted the unit in installing the equipment and providing after-sales services. We also informed the unit in detail of the relevant precautions. The unit expressed great satisfaction with our equipment and services. The monitoring of hydrological water quality and rainfall is very important data for environmental protection and management. Increasing data monitoring in this area will greatly help with environmental management.
