MMD1002E Module Industrial Grade Electrochemical Ammonia Gas Sensor NH3 Odor Gas Detection
Product Applications:
- Civilian Scenarios: It is mainly used in places where ammonia is prone to accumulate, such as smart public toilets, residential area garbage stations, garbage incineration plants and sewers. It can monitor ammonia concentration in real time. When the concentration reaches a certain threshold, it can link with the fresh air system to trigger automatic ventilation, thus improving the air quality.
- Industrial & Special Scenarios: It is suitable for mining operations. It can stably work in harsh mining environments with large temperature differences and heavy dust to detect ammonia leaks in a timely manner. In addition, it can also be used in wastewater treatment facilities, refrigeration plants and other industrial sites where ammonia may leak, providing a reliable guarantee for staff safety and environmental protection.
Product Features:
- Strong Environmental Adaptability: The dust - resistant filter design ensures stable operation in dusty environments. The temperature and humidity compensation mechanism allows it to work reliably whether in the high - temperature and stuffy deep mines or in the cold and humid underground working areas.
- Convenient Integration and Use: With pre - calibration before leaving the factory, it can be put into use quickly after being connected to the system. The dual output modes of digital and analog voltage make it easy to connect with various intelligent control devices and systems, reducing the difficulty of secondary development for users.
- Reliable Early Warning Performance: It can quickly detect the concentration of ammonia gas and output accurate data in a short time. This enables early detection of ammonia leaks, which helps relevant personnel take evacuation or leak - repairing measures in time, avoiding health hazards to the human body caused by excessive ammonia inhalation.
