How to Ensure the Operational Stability of Multi-gas Detectors
The composite gas detector is a flexible single or multiple gas detector that can be equipped with oxygen sensors, combustible gas sensors, and optional two toxic gas sensors or optional four toxic gas sensors or optional single gas sensors. It has the advantages of fast response speed, good stability, high sensitivity, small size, light weight, and easy portability. During the use of the composite gas detector, in order to ensure the stability of equipment operation, users should pay attention to the following requirements:
1. When the composite gas detector is not in use, it should be placed in a dry and ventilated place to avoid being placed together with corrosive substances to accelerate aging and shorten the service life of the gas detector.
2. Check the gas flow rate, usually 30/h, as excessive or insufficient flow rate can have a significant impact on the analyzer results
3. Replace filter paper: Stop the air pump and drain the filter tank
4. Check for any air leaks in the pneumatic system. Whether the diaphragm of the sobbing pump is damaged, whether the sealing ring of the sampling probe is broken, whether the four-way valve and condensate are damaged, etc
5. Cleaning of sampling probe, unblocking of sampling hole pipeline
6. Check if the condenser is working properly, usually adjust the temperature within the range of 3 degrees Celsius
7. Check the measuring room for dirt and clean it promptly.
Determine the usage scenario:
According to different industrial environments, we can divide gas detectors into three types: fixed gas detectors, portable gas detectors, and composite gas detectors. Among them:
1) Fixed gas detector: Fixed gas detectors can be installed at specific detection points to detect specific gas leaks. They are generally two-piece, with a detection head composed of sensors and transmitters installed as a whole at the detection site, and a secondary instrument composed of circuits, power supplies, and display alarm devices installed as a whole in a safe place for easy monitoring.
2) Portable gas detector: Portable gas detectors have the advantages of easy operation, compact size, and can be carried to different production sites. If used in open environments such as open workshops as safety alarms, portable diffusion gas detectors can be used because they can continuously, real-time, and accurately display the concentration of toxic and harmful gases on site; If entering a confined space, such as reaction tanks, storage tanks or containers, sewers or other underground pipelines, underground facilities, agricultural enclosed grain warehouses, railway tankers, shipping cargo holds, tunnels, etc., personnel must undergo testing before entering, and testing must be conducted outside the confined space.
3) Composite gas detector: The composite gas detector can be equipped with multiple gas detection sensors on one instrument, so it has the characteristics of small size, light weight, fast response, and simultaneous display of multiple gas concentrations. Compared with general gas detectors, it is also more convenient to use.
