Gas & Air Quality Sensors

Even under harsh conditions such as high temperature and humidity or complex background gases, this series maintains long-term stable data output. It is widely used in smart home fresh-air systems, in-vehicle cabin monitoring, industrial hazardous-chemical leak alarms, and smart-city grid-based environmental management. Through precise air data, we help customers move from passive protection to proactive control, building a solid defense for human health and industrial safety.

CO (Carbon Monoxide) Sensors

Use electrochemical or metal-oxide principles to accurately monitor toxic concentrations in air. They are core components for home heating safety, underground garage ventilation, and early fire warning.

CO2 (Carbon Dioxide) Sensors

Primarily based on non-dispersive infrared (NDIR) technology. Widely used in fresh-air systems, greenhouse cultivation, and office environments, they enable intelligent energy saving and air optimization through concentration monitoring.

O2 (Oxygen) Sensors

Usually based on electrochemical or zirconia principles. They monitor confined-space safety, medical ventilators, and industrial combustion efficiency in real time, making them indispensable for life safety and combustion optimization.

VOCs Sensors

Use metal-oxide semiconductor or PID detection technologies. They sensitively capture the total presence of formaldehyde, benzene, and other harmful gases, serving as key components for indoor air purifiers and renovation pollution monitoring.

H2S (Hydrogen Sulfide) Sensors

Designed for highly toxic and corrosive environments with very fast response. Widely used in sewer operations, refineries, and the paper industry, they help protect personnel entering hazardous areas.

NH3 (Ammonia) Sensors

Monitor concentrations of irritating gases in real time. They are mainly used for ventilation control in livestock farming, ammonia refrigeration leak alarms in cold storage, and chemical process monitoring.

SO2 (Sulfur Dioxide) Sensors

Highly sensitive electrochemical sensors designed for harsh environments. Widely used in desulfurization monitoring at thermal power plants, boiler flue-gas analysis, and smart-city atmospheric quality grid supervision.

H2 (Hydrogen) Sensors

Highly sensitive hydrogen sensors designed for reliable leak detection in demanding environments. Widely used in hydrogen production and storage facilities, fuel-cell systems, battery rooms, industrial gas monitoring, and explosion-risk safety applications.

NO (Nitric Oxide) Sensors

High-performance nitric oxide sensors for precise monitoring in industrial and environmental applications. Suitable for combustion control, boiler and furnace emissions analysis, vehicle exhaust testing, and continuous air-quality monitoring.

Combustible Gas Sensors

Reliable combustible gas sensors for early leak detection and explosion-risk monitoring. Ideal for industrial plants, oil and gas facilities, chemical processing areas, boiler rooms, and confined-space safety systems.

Gas Sensor Modules

Compact gas sensor modules integrating sensing elements, signal conditioning, and calibrated output. Suitable for portable detectors, environmental monitoring equipment, smart appliances, industrial safety systems, and IoT-based air-quality applications.
