Industrial Safety Monitoring: It is widely used in industries such as petrochemical, coal mining, etc. In coal mines, it can accurately detect the content of carbon monoxide underground to ensure the safety of miners. In petrochemical plants, it is used to monitor the carbon monoxide concentration in the production process to prevent poisoning accidents.
Environmental Protection Monitoring: It can be used for urban environmental monitoring, helping to monitor the carbon monoxide content in the atmosphere, and providing data support for environmental protection departments to make relevant policies.
Gas Detection in Confined Spaces: It is applicable to gas detection in confined spaces such as tunnels and indoor parking lots. For example, in tunnels, it is used to monitor the carbon monoxide concentration in the air to ensure the air quality and the safety of construction and passing personnel.
Characteristics:
Wide Measuring Range: The measuring range is 0 - 5000 ppm, and the maximum overload can reach 10000 ppm, which can meet the needs of different environments for carbon monoxide concentration detection.
High Sensitivity: The sensitivity range is 55 - 90 nA/ppm, which can accurately detect the change of carbon monoxide concentration, even a very low concentration of carbon monoxide can be detected.
Fast Response: The response time is less than 25 seconds (T90), which can quickly respond to the presence of carbon monoxide and provide timely warning information.
Good Linearity: The output signal is linear, with a full - scale linear error of 15 - 25 ppm, which is convenient for data processing and analysis, and the measured value can be more accurately reflected.
Small Size: The size is Φ20.2*16.5 mm, which is small and lightweight, easy to install and integrate into various detection equipment, and can be made into portable detection instruments or fixed - type alarm instruments.
Long - term Stability: The annual change of the equivalent zero - point in laboratory air is less than 0.2 ppm, and the monthly sensitivity drift in laboratory air is less than 8% change/year, with good long - term stability and can maintain reliable performance during the service life.
Certain Anti - interference Ability: It has a certain anti - interference ability, with a H2S filter capacity of 250,000 ppm·h, a NO2 filter capacity of 2,600,000 ppm·h, etc., which can reduce the interference of other gases and improve the accuracy of measurement.
