"JJF 1699-2018 Mine Carbon Monoxide Detection Alarm Type Evaluation Outline" is suitable for evaluating the electrochemistry principle of carbon monoxide detection alarms used in mines. This outline refers to a number of environmental test method standards, including low temperature, high temperature and alternating humidity cabinet tests, to ensure the Reliability and Stability of the detection alarm under various harsh environment conditions. The detection alarm is used to monitor the concentration of carbon monoxide gas in the mine operating environment. Once the concentration exceeds the set value, it can be automatically alarmed by sound and light signals. Its main components include carbon monoxide Electrochemical sensors, electronic components and display devices. Sensors convert the detected gas concentration into an electrical signal and display the concentration value after processing. Depending on the mode of use, the detection alarm is divided into portable and fixed, and the fixed device can also output the corresponding concentration signal, which is suitable for long-term monitoring and safety management needs.
