Kyushu Space explains how to buy a gas detector
Gas detectors are mainly used for the detection of toxic, harmful and combustible gases. The toxic gas detectors are used in coal mines, petroleum, chemical, gas transmission and distribution, biochemical medicine, agricultural pesticides, building materials, coking, building materials and other fields. There are applications.
For all kinds of different production occasions and testing requirements, the choice of a suitable gas detector is a must for every person engaged in safety and health work. Here we will give an introduction to the specific use of some gas detectors for your reference.
1) The gas detector should first confirm the type and concentration range of the gas to be tested:
The type of gas encountered in each production department is different. All possible situations should be considered when selecting a gas detector. If methane and other less toxic alkanes are the most common, the LEL detector is the most suitable. This is not only because the LEL detector has a simple principle and a wide application, but it also has the characteristics of convenient maintenance and calibration. If there are toxic gases such as carbon monoxide and hydrogen sulfide, it is necessary to select a specific gas detector to ensure the safety of workers. If there are more organic toxic and harmful gases, considering the low concentration of people who may cause poisoning, such as aromatic hydrocarbons, halogenated hydrocarbons, ammonia (amines), ethers, alcohols, fats, etc., photoionization detection should be selected. Never use the LEL detector, as this may result in personal injury or death. If the gas type covers the above types of gases, choosing a compound gas detector may achieve a multiplier effect.
2) Determining the use occasion: The type of gas detector is different depending on the industrial environment.
A) Fixed gas detector: This is a detector that is used more on industrial equipment and in the production process. It can be installed at a specific inspection point to detect specific gas leaks. The fixed detector is generally two-piece type. The detection head consisting of sensor and transmission is installed in the inspection site. The secondary instrument consisting of circuit, power supply and display alarm device is installed in a safe place for easy monitoring. Its detection principle is the same as that described in the previous section, but it is more suitable in the process and technology for the continuous and long-term stability required for fixed detection. They are also selected according to the type and concentration of the gas on site, and care should be taken to install them where the specific gas is most likely to leak, such as selecting the most effective height for sensor installation based on the specific gravity of the gas.
3) Portable gas detector: Because the portable instrument is easy to operate and compact, it can be carried to different production sites. The electrochemical detector is powered by alkaline battery and can be used continuously for 1000 hours. The new LEL detector, PID and compound instrument Rechargeable batteries (some have used non-memory nickel-metal hydride or lithium-ion batteries), so they can work continuously for nearly 12 hours, so gas detectors are increasingly used as instruments of this type in various factories and health departments. wide.
Gas detectors, also known as gas alarms, can be used with a diffused gas detector that is worn in an open environment, such as an open work shop, as it can be displayed continuously, in real time, and accurately. The concentration of toxic and harmful gases on site. Some of these new instruments are also equipped with vibration alarm accessories - to avoid audible alarms in noisy environments, and computer chips to record peaks, STEL (15 minute short-term exposure levels) and TWA (8-hour statistical weights) Average) - Provides specific guidance for worker health and safety.
If it is entering a confined space, such as a reaction tank, storage tank or container, sewer or other underground pipeline, underground facilities, agricultural closed granary, railway tanker, shipping cargo bay, tunnel, etc., it must be tested before personnel enters. And to test outside the confined space. In this case, you must select a multi-gas detector with a built-in sampling pump. Because the gas distribution and gas type of different parts (upper, middle and lower) in the confined space are very different. For example, in general, the proportion of combustible gases is relatively light, and most of them are distributed in the upper part of the confined space; the specific gravity of carbon monoxide and air is similar, generally distributed in the middle of the confined space; and the heavier gases such as hydrogen sulfide are present in the confined space. The lower part of the space. At the same time, the oxygen concentration is also one of the types that must be detected.
In addition, a gas detector that can detect organic gases is also needed if one considers the volatilization and leakage of possible organic matter in the tank. Therefore, a complete confined space gas detector should have a built-in pumping function - so that it can be non-contact, sub-site detection; with multi-gas detection function - to detect different spatial distribution of dangerous gases, including inorganic and organic gases With oxygen detection function - to prevent hypoxia or oxygen enrichment; portable device that is small in size and does not affect workers' work. Only in this way can the absolute safety of the personnel entering the confined space be guaranteed. In addition, after entering the confined space, the gas components therein should be continuously tested to avoid changes in the concentration of volatile organic compounds or other toxic and harmful gases caused by personnel entering, sudden leakage, and temperature changes. If used for emergency, leak detection and inspection, pumping, short response time, high sensitivity and high resolution instruments should be used to make it easy to determine the location of the leak.
