The radon monitor is a precision instrument for detecting the concentration of radon gas in the environment. It uses a highly sensitive radon gas sensor to accurately measure the radon content in indoor and outdoor air. The outer shell is designed compactly and is usually made of sturdy and durable metal or plastic materials with good sealing properties to effectively prevent external interference. Its advantage lies in its high detection accuracy and good stability, enabling long - term continuous monitoring of radon gas concentration changes and providing people with accurate radon exposure information. It is widely used in places such as homes, offices, schools, and basements. In homes, it safeguards the health and safety of residents; in offices and schools, it creates a healthy working and learning environment; in basements, it prevents potential hazards caused by radon gas accumulation.
