Nitric oxide (NO) is a colorless and odorless gas, mainly from fuel combustion and industrial production processes, such as thermal power plants, automobile exhaust, etc.NOSignificant hazards to human health and the environment:

       1.Health Hazards:NOAfter entering the human body, it will combine with hemoglobin, reduce the oxygen carrying capacity of blood, cause hypoxia symptoms, and may cause respiratory diseases or even death in severe cases;

       2.Environmental Hazards:NOIn the atmosphere, it reacts with oxygen to produce nitrogen dioxide (NO2), further forming acid rain and photochemical smog, causing damage to ecosystems and buildings.

to avoidNOThe following measures should be taken:

       1.Strengthen industrial emission control: by optimizing the combustion process, installing exhaust gas treatment equipment (suchSCRcatalyst) decreaseNOemissions;

2. Personal protection: In the environment that may be exposed to NO, the operator should wear a gas mask and a positive pressure respirator, and conduct regular health checks.

NOGas electrochemical sensors play an important role in many fields due to their high sensitivity, fast response and stability:

       1.Environmental monitoring: for real-time monitoring of atmosphericNOconcentration, assess air quality, and provide data support for pollution control;

       2.Industrial process control: in the chemical, petroleum and other industries, the sensor can monitor the production processNOThe generation, optimization of process parameters, to ensure safe production;

       3.Healthcare: In medical devices such as ventilators, sensors are used to monitorNOConcentration, auxiliary diagnosis of respiratory diseases.

In the chemical industry,NOThe role of gas electrochemical sensors is particularly prominent:

       1.Real-time monitoring and early warning: Sensors can be monitored in real time by being deployed around production plants and near critical equipmentNOConcentration changes, once a leak is detected, immediately issue an alarm, start the ventilation system or emergency shutdown to avoid accidents;

       2.Optimize the production process: The sensor can help adjust the reaction conditions, improve the yield and product quality. For example, in the nitric acid production process, real-time monitoringNOThe concentration helps to optimize the reaction efficiency;

       3.Environmental compliance: Chemical companies need to meet strict environmental standards, and sensors can monitor emissions.NOConcentration, to ensure that enterprises meet emissions standards, to avoid environmental pollution.
