Negative oxygen ions exert a significant impact on the physiological activities of the human body, and their effects are mainly realized through the nervous system and blood circulation process. For this reason, the concentration of negative oxygen ions in the air has become one of the key indicator...
In scenarios such as ventilation and air conditioning systems and industrial pipeline exhaust, the air velocity in the air duct is an important parameter for measuring the operating status of the system. When the air velocity is too high, it may lead to increased energy consumption, greater pipeline...
Surface water quality monitoring uses five standard parameters—water temperature, pH, dissolved oxygen, conductivity, and turbidity—for continuous real-time data collection via online automatic monitoring stations or portable multi-parameter analyzers. This provides fundamental data support...
