The gas detector can be used to detect the types of gases present in the environment. According to the detection results, use the corresponding Safety protective equipment.Different industrial environments require different types of gas detectors.
A) Fixed gas detection proposal:
This is a detector commonly used in industrial equipment and production processes. It can be installed at specific detection points to detect specific gas leaks. Fixed gas detectors are generally split type. The gas detection detector is installed at the detection site, and the secondary instrument consisting of circuit, power supply and display alarm device is installed in a safe place for easy monitoring. Fixed gas detectors have the characteristics of continuous and long-term stability. They should also be selected according to the type and concentration of the gas on site. At the same time, attention should be paid to installing them in the parts where specific gases are most likely to leak. For example, the most effective height should be selected based on the specific gravity of the gas, etc.
B) Portable gas detector:
Because the portable gas detector is easy to operate and small in size, it can be carried to different production areas. The detector detects gas concentration by natural diffusion and uses imported sensors. The menu operation is simple and can be used by people with different habits. It has an ergonomic design and a good grip. Comfortable and easy to operate. The portable gas detector can save 3,000 alarm records and has a 1,500mAh large-capacity lithium battery, which greatly improves the battery life of the device. It uses a USB interface for charging and is convenient for charging with a universal charger.
If you enter a confined space, such as a reaction tank, storage tank or container, sewer or other underground pipeline, underground facility, agricultural closed granary, railway tanker, shipping cargo hold, tunnel and other workplaces, testing must be carried out before personnel enter. , and the detection must be carried out outside a confined space. At this time, 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) of the confined space are very different. For example: Generally speaking, combustible gases have a lighter specific gravity and are mostly distributed in confined spaces. Carbon monoxide and air have similar specific gravity and are generally distributed in confined spaces, while heavier gases such as hydrogen sulfide exist in confined spaces. The lower part of the space (as shown in the picture). At the same time, oxygen concentration is also one of the types that must be detected.
When using a gas detector, you must pay attention to the usage 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 results detected by the gas detector may drift. In this case, we should perform on-site zero calibration of the gas detector, which can minimize the impact of temperature on the gas detector. impact on results.
If the air humidity in the working space increases, the water vapor in the air will drive away oxygen, causing the oxygen reading to drop. This effect will not be noticed immediately, but will slowly affect the oxygen level over several hours and affect the test results. Therefore, when we inspect the air, we must pay attention to the temperature and humidity of the air in the working air in order to adjust the detector.
