7NO-5 Nitric Oxide Gas Sensor For Industrial And Environmental Monitoring

• Usage:
  • Medical diagnosis: It is mainly used for the detection of fractional exhaled nitric oxide (FeNO). When the body is in an inflammatory state caused by airway diseases, the content of exhaled nitric oxide will increase. Therefore, FeNO detection is widely used in the diagnosis and monitoring of airway inflammatory diseases, which can help identify chronic airway diseases such as chronic obstructive pulmonary disease (COPD), asthma, and asthma - COPD overlap syndrome, and can also predict the treatment effect and prognosis of COPD patients.
  • Industrial and environmental monitoring: It can be used to measure the concentration of nitric oxide in the gas phase, and is applied to environmental monitoring of industrial waste gas emissions, air quality monitoring in factories and workshops, etc., to ensure that the content of nitric oxide in the air meets the environmental protection standards and safety requirements. In addition, it can also be used in some occasions where nitric oxide gas is produced or used, such as chemical plants, to monitor the leakage and concentration changes of nitric oxide in real - time.
  • Medical treatment equipment: It is used in nitric oxide therapy equipment, also known as nitric oxide inhalation therapy equipment. This kind of equipment is used to inhale nitric oxide for patients to treat diseases. The gas sensor can accurately detect the concentration of nitric oxide to ensure the safe and reliable operation of the treatment process.
• Features:
  • High - precision detection: The 7 - series NO gas sensors usually adopt a four - electrode structure design. Through the compensation algorithm, they can improve the accuracy of low - concentration gas measurement, and some sensors can achieve a resolution of 5 ppb or even higher, providing a guarantee for trace - level detection.
  • Fast response: The response time (T90) of the sensor is relatively short, generally less than 30 seconds, and some sensors can be as short as 15 seconds, which can quickly detect the change of nitric oxide concentration and provide real - time data. At the same time, the recovery time is also fast, which can quickly return to the baseline, facilitating continuous detection.
  • Good stability: It has strong environmental stability, and the baseline shift is small within the temperature range of - 20℃ to 50℃. The long - term output drift is less than 2% of the signal per month, and the expected service life in clean air is about 2 years, which can maintain relatively stable performance during long - term use.
  • Strong anti - interference ability: It can resist the interference of some other gases to a certain extent. Although there may be cross - sensitivity to some gases, through reasonable design and algorithm compensation, the impact on the detection of nitric oxide can be minimized.
  • Low power consumption: With the advantages of low power consumption, it is suitable for various portable or battery - powered detection equipment, reducing energy consumption and facilitating field use.
