Reliable refrigerant gas detection ensures safety and sustainability, preventing leaks that harm workers and the environment while ensuring regulatory compliance in industrial settings  Refrigerant gases are widely used in industrial refrigeration, HVAC and air conditioning systems. However, accidental leaks can pose a risk to safety and the environment. Some of these gases, such as hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs), contribute to the greenhouse effect and ozone layer depletion, while others, such as ammonia (NH₃) and carbon dioxide (CO₂), can be
