2 years warranty data accuracy NH3 sensor








product description
In modern production, for example, the production of compound fertilizers, the synthesis of ammonium salts, and the like require the use of liquid ammonia. Sulfonamides, polyurethanes, polyamide fibers, and nitrile rubbers are all required to directly use ammonia as a raw material. However, the leakage of ammonia gas in an environment with poor air circulation can burn people's skin, eyes, and mucous membranes of respiratory organs. If the concentration is too high, it may cause lung swelling and death. When the ammonia gas leakage concentration is between 16% and 25%, an explosion may occur even at normal temperature. In order to ensure the health and life safety of the human body, our company has developed an ammonia temperature and humidity transmitter for the detection of ammonia concentration.

The transmitter uses the electrochemical principle to detect the concentration of ammonia (NH3). The reaction is rapid, sensitive, low-power, high-precision, anti-interference, and has excellent repeatability and stability. The product adopts 485 communication standard MODBUS-RTU communication protocol, communication address and baud rate can be set. Ammonia gas is a toxic gas. If the concentration is too high, it will cause harm to the human body. This product is widely used in real-time detection of ammonia in industrial, mining, chemical, fertilizer, pharmaceutical, material synthesis and environmental protection. The enclosure rating is high and can be adapted to different environmental monitoring.
