How does a handheld hydrogen leak detector work?

        The installation method and precautions of the fixed hydrogen sensor are as follows:        First, installation method:        1. Location selection: According to the point where hydrogen may leak, select a location that is easy to detect and will not be interfered with by other gases.        2. Fixed installation: Use a suitable mounting bracket or bracket to ensure that the sensor is stable and avoid vibration.        3. Wiring and debugging: Wiring correctly according to the wiring diagram provided by the manufacturer, including power cord, signal output line, etc., and initial calibration and debugging.        4. Environment adaptation: Ensure that the installation environment meets the requirements of the sensor operating temperature and humidity. Take measures to prevent dust and water if necessary.        Second. Precautions:        1. Ensure that no obstacles block the detection range of the sensor.        2. Check the working status of the sensor regularly and clean the surface of the sensor.        3. Ensure that the installation environment is properly grounded according to the electrical safety regulations.        4. Avoid installation in direct sunlight or in an environment with rapid temperature changes.        The common faults and solutions of fixed hydrogen sensors are as follows:        1. Signal drift or instability: Calibrate the sensor regularly, check and clean the sensor, and replace the sensor if necessary.        2. If no signal is generated, check whether the power cable and signal cable are connected properly and whether the power supply is stable.        3. Slow response: Check whether the sensor needs to be cleaned or replaced, and confirm whether the detection environment meets the conditions for the use of the sensor.        4. False alarm: Check whether there is other gas interference, adjust the sensor sensitivity or replace a more specific sensor.
