    Fixed Hydrogen Sulfide (H2S) Gas Detector Details

    Tips: Installation of Fixed Hydrogen Sulfide (H2S) Detector

    A fixed nitric oxide (NO) gas detector is a device specially designed to monitor the concentration of nitric oxide gas in the environment. The gas leak detectors are widely used in industrial, chemical, gas, environmental protection, and medical fields to ensure that the concentration of nitric oxide is within a safe range and to sound an alarm once the concentration rises.

    Working Principle and Composition

    1. Sensor: Fixed NO gas detectors are usually equipped with nitric oxide gas sensors. Common gas sensor types include electrochemical sensors, optical sensors, and chemical sensors. These gas sensors work on different principles, but all detect the presence of nitric oxide molecules.
    2. Data Acquisition: The gas leak detector sensor generates an electrical signal or other sensing signal by detecting the concentration of nitric oxide gas in the surrounding environment.
    3. Data Processing: The generated signals are fed into a built-in microprocessor or control unit for data processing and analysis.
    4. Alarm Systems: Gas monitors are often equipped with gas alarm systems with sound, light, or digital interfaces, and often the ability to transmit information to a monitoring center. When the nitric oxide concentration exceeds the set safety threshold, the gas alarm system is triggered to notify the operator to take necessary measures.
