Different industrial environments require different types of gas detectors.
A) Fixed gas detection protocol:
This is a detector that is widely used in industrial devices and production processes. It can be installed on a specific detection point to detect specific gas leaks. The fixed gas detector is generally a split type. The gas detection detector is installed at the detection site, and the secondary instrument composed of a circuit, power supply and display alarm device is installed in a safe place as a whole, which is convenient for monitoring. The fixed gas detector has the characteristics of continuous and long-term stability. They should also be selected according to the type and concentration of the on-site gas, and at the same time, attention should be paid to installing them in the most likely place for a specific gas to leak, such as choosing the most effective height according to the specific gravity of the gas, and so on.
B) Portable gas detector:
Because the portable gas detector is easy to operate and small in size, it can be carried to different production sites. The detector uses natural diffusion to detect gas concentration. It uses imported sensors. The menu is easy to operate and can be used by people with different habits. Ergonomic design, grip feeling Comfortable and easy to operate. The portable gas detector can save 3000 alarm records, a 1500mAh large-capacity lithium battery, which greatly improves the battery life of the device; it is charged with a USB interface, and it is convenient to charge with a universal charger.
If this type of instrument is used as a safety alarm in an open place, such as an open workshop, a portable diffusion gas detector can be used because it can continuously, in 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 pipes, underground facilities, agricultural closed granaries, railway tank cars, shipping cargo holds, tunnels, and other workplaces, inspections must be carried out before personnel enters, and the detection should be carried out outside the confined space. At this point, it is necessary to choose a multi-gas detector with a built-in sampling pump. Because the gas distribution and gas types in different parts (upper, middle, and lower) in the confined space are very different. For example, the specific gravity of combustible gases in the general sense is relatively light, and most of them are distributed in closed spaces. Carbon monoxide and air have similar specific gravity and are generally distributed in closed spaces, while heavier gases such as hydrogen sulfide exist in closed spaces. The lower part of the space (as shown). At the same time, the oxygen concentration is also one of the types that must be detected.
The gas detector is one of the most commonly used detection instruments in industrial production. It can detect the concentration of toxic and harmful substances in our work. The gas detector can detect the types of gases existing in the environment. According to the detection results, use the corresponding Safety protective equipment. When using a gas detector, you must pay attention to the use environment. There are many factors that can affect the detection results of the gas detector, such as changes in humidity and temperature.
Changes in temperature affect the amount of oxygen actually present in the atmosphere. If the temperature in the working space fluctuates greatly, the detection results of the gas detector may drift. impact on the outcome.
If the air humidity in the working space increases, the water vapor in the air will drive away the oxygen, which may cause the oxygen reading to drop. This effect will not be noticed immediately, but it will gradually affect the degree of oxygen after several hours and affect the test results. Therefore, when we inspect the air, we should pay attention to the temperature and humidity of the air in the working air in order to adjust the detector.
