With the rise of modern sealed buildings, there is a growing concern about the accumulation of harmful substances like volatile organic compounds (VOC), particulate matter (PM), and carbon dioxide (CO2). Extended exposure to such substances can lead to respiratory problems, allergies, and various health concerns. By closely monitoring the quality of indoor air, prompt actions can be taken to enhance ventilation and purification, thereby protecting the health of individuals in both residential and commercial environments.

HVAC control function is designed to maximize energy efficiency, reduce energy consumption and decrease operating expenses for modern buildings. HVAC control function improves indoor comfort by intelligently managing temperature, humidity, and air quality levels to provide a healthier and more convenient indoor environment.

Sustaining high levels of product quality and cleanliness requires cleanroom monitoring. Cleanrooms are widely used in industries such as semiconductors, pharmaceuticals, Li-battery production, and flat panel display manufacturing, where even tiny contaminants can severely impact product performance and quality. Cleanroom monitoring with optical particle counters can help identify and eliminate potential sources of contamination, ensuring the production environment meets stringent industry standards.

Safety alarm is crucial for detecting indoor harmful gases, reducing significant health risks, environmental pollution, and equipment damage. Carbon monoxide is a colorless, odorless toxic gas that can cause poisoning and even death at high concentrations. Natural gas is a common combustible gases of which leaks can lead to fires or explosions. Additionally, refrigerant gas leaks not only affect the efficiency of HVAC/R equipment but can also harm the environment and health.
