Soil is a key natural resource and is vital for crop growth. Crops are affected by dry or excessively wet soils, and economic and social development and climate change have exacerbated the problem of drought, leading to increased water scarcity and associated disaster losses. In hilly and forested a...
In the daily operation of wastewater treatment plants, ammonia nitrogen detection is essential. Ammonia nitrogen refers to the nitrogen present in water in the form of free ammonia (NH3) and ammonium ions (NH4+). Excessively high ammonia nitrogen levels can deplete dissolved oxygen in water bodies,...
Rainfall monitor is specially designed for flash flood and meteorological disaster early warning. It is easy to install, has low power consumption, long wireless transmission distance and low maintenance cost. It can conduct detailed minute-level monitoring of rainstorms. These stations are located...
What is the rain Gauge is a tool that measures the amount of rainfall in a specific area over a period of time and is used to determine the depth of precipitation occurring over a unit area....
