Applications
Semiconductor and Electronics Manufacturing
Monitor trace contaminant gases (such as NH3, HCl, HF, VOCs, etc.) in cleanrooms and during the process to ensure the purity of the process environment and product yield.
Power Transformer
Real-time monitoring of characteristic gases inside oil-immersed power transformers (such as C2H2,H2, etc.) to achieve insulation aging and early fault warning.
GIS Fault Warning
Real-time monitoring of the purity of SF6 gas and its decomposition products (such as SO2, H2S, CO, HF, etc.) in gas-insulated switchgear(GIS) to provide early warnings of internal discharge or overheating faults in the equipment.
Catalyzation
Monitoring gases in catalytic reactions, such as CH2O,C6H5CH3,(CH3)2CO, CO2, CO, NOₓ, and NH3, to enable catalytic efficiency assessment.
Husbandry
Monitoring the air quality of shelters and the livestock emissions such as methane, carbon dioxide, ammonia, etc.
Ambient air monitoring
Monitoring hydrogen fluoride (HF), ammonia and formaldehyde, etc. in ambient air.
Border security
Detecting trace-level illicit substances and signature volatile organic compounds (VOCs) such as MDMA, cocaine, amphetamines, drug precursors, as well as explosives such as nitrotoluene and nitroglycerin.
Cargo container safety
Detecting hazardous chemicals sealed in cargo containers include fumigants and VOCs.
Thermal runaway
