Buy Gas Detection Companies From Zetron

In today's world, environmental monitoring is the foundation and technical support for environmental management. With the development of my country's environmental protection work, my country's environmental monitoring technology has also made great progress, and the production of environmental monitoring instruments has formed a certain scale. The four-in-one gas detector is a single gas or multiple gas detectors that can be flexibly configured. It can be equipped with an oxygen sensor, a combustible gas sensor, and optionally two toxic gas sensors or optionally four toxic gas sensors or any Choose a single gas sensor.








We know that the conventional four-in-one gas detector can detect four gases: oxygen, combustible gas, hydrogen sulfide, and carbon monoxide. Of course, we can also customize it according to the gas we need to detect. The four-in-one gas detector has a very clear large liquid crystal display screen, with sound and light alarm prompts, to ensure that dangerous gases can be detected in a very unfavorable working environment and promptly prompt the operator to prevent.







The general detection parameters and range of the four-in-one gas detector are as follows:

Can detect 1～4 kinds of gas at the same time, the unit can be switched freely

Units are optional: PPM, mg/m3, Vol%, LEL%, PPHM, ppb, mg/L.

★ Rich man-machine interface

2.31-inch high-definition color screen, displaying real-time concentration, alarm, time, temperature, humidity, storage and other information; the menu interface uses high-definition simulation graphics to display the function name of each menu.

★ Large-capacity data storage function (capacity can be customized), supports multiple storage methods, optional RS485 communication

About high efficiency filter leak detection: For food and drug manufacturers, high efficiency filter leak detection refers to the on-site leak detection after the installation of high efficiency filter and its system, mainly to check the small pinholes and other damages in the filter material, such as frame seal, gasket seal and leaky seams on the filter frame. The purpose of leak detection is to check the sealing of the high efficiency filter and its connection parts with the installation frame, find the defects in the high efficiency filter itself and in the installation in time, and take corresponding remedial measures to ensure the cleanliness of the area. Whether there is leakage. The purpose of dust generation is that the dust concentration upstream of the high efficiency filter is low, so if a particle counter is used to detect the leak without dust generation, it is difficult to detect the leak, and additional dust generation is needed to obviously and easily detect the leak.

Note: Heating occurs when oily particles are heated and evaporated and then blown into the system air inlet by inert gas, suitable for the end of the whole air conditioning system for high efficiency filter detection, the advantage is that the whole system only needs a place to produce dust , after the filter upstream concentration is stable, you can test the filters one by one, reducing the time of frequent change of dust production points and debugging dust concentration, also saves the PAO oil for debugging. The disadvantage is that there should be a long section of mixed cold generation ten times the diameter of the air duct, which is not suitable for local FFU units without air supply duct at the top, and not suitable for single biosafety cabinets and clean benches.



Cold generation is made of compressed air and pressurized PAO oil, which is sprayed by Laskin nozzles, and the working number of nozzles is used to adjust the size of dust concentration, which is suitable for local FFU units and clean benches of biosafety cabinets without air supply ducts. There is no thermal occurrence of the convenience, there are also air conditioning systems because of the inconvenience of segmentation detection, and can not use this type of dust generation small amount of dust generation instrument.

Lithium batteries are also called lithium-ion batteries, the world's first lithium-ion battery was produced and commercialized by Sony in 1991.

Compared with other rechargeable batteries such as lead-acid batteries and nickel-cadmium batteries, lithium-ion batteries have the advantages of high energy density, relatively safe to use, no memory effect, and do not contain lead, cadmium, mercury and other heavy metal elements that pollute the environment, so it is a more environmentally friendly battery.




The Ministry of Industry and Information Technology (MIIT) promulgated the "New Energy Vehicle Industry Development Plan (2021-2035)" in 2019, which states that the domestic new energy vehicle sales ratio is expected to reach 25% and the intelligent networked vehicle sales ratio to reach 30% by 2025.







Internationally, Europe has introduced the strictest carbon emission law, which will prompt major car companies to accelerate the transition to electrification, and European countries have adopted policies of direct subsidies and tax breaks to promote the long-term development of the industry.



The lithium battery industry chain is divided into upstream materials, midstream lithium-ion batteries and downstream consumer electronics, new energy vehicles and energy storage.



The upstream of the industry chain is the mining and processing of raw material resources, mainly including cobalt, lithium, graphite materials, carbon materials, etc.

The upstream mainly includes cathode materials (lithium carbonate, lithium cobaltate, ternary materials, etc.), anode materials, electrolyte, diaphragm, and other auxiliary materials.



The midstream of the industry chain mainly refers to core manufacturing and modules, connecting upstream core production and downstream vehicle applications.

According to the data in 2020, the power battery installed volume of the top 10 power battery enterprises is 58.4GWh, accounting for 92% of the total installed volume. Enterprises include Ningde Time, Kodaly, Xinwanda, Yiwei Lithium Energy, BYD, and Guoxuan Hi-Tech, etc.



The downstream of lithium battery industry chain includes consumer electronics, new energy vehicles and energy storage.

New energy vehicles are an important thrust of the current lithium battery industry explosion, with new energy vehicle sales rising from 330,000 to 1.21 million units from 2015-2019. The future demand for power batteries for new energy vehicles will continue to grow, and this will greatly increase the market demand for lithium batteries.

In addition, the application of lithium batteries in the field of electric bicycles and energy storage is also developing faster.



Lithium battery production accidents


In addition to the safety of the finished battery, we are also very concerned about the safety of the battery production process. When the electrolyte of lithium battery encounters a large amount of water, it may explode due to rapid decomposition and exotherm. In the working environment of lithium battery factory, there are flammable gas or toxic gas leaks, such as ammonia, CL2, HF, hydrogen sulfide, hydrogen, carbon monoxide, hydrochloric acid, Freon, phosphoric acid, etc. The concentration of these gases exceeds the standard, there will be fire, poisoning and other dangerous hazards.








The process of environmental testing, when the battery is broken, the possibility of CO, H2, H2S leakage will occur, the site distribution and installation of fixed gas detector MIC500, MIC600 can be online detection of leaking low concentration of gases.



Fixed gas detector is suitable for detecting the content of carbon monoxide, hydrogen sulfide and other toxic gases in the gas leakage area. The product adopts the integrated design of sound and light alarm, which can effectively warn the danger of various gas leaks and protect the personal safety of operators.

The gas detectors have their own working conditions. You need to pay attention to the basic conditions of humidity, temperature, and pressure. Generally, the installation in our environmental plant is more suitable. Basically, it can be directly installed and fixed, but we install it in a confined space. 








 Such as pipes, flues, in these special environments, we must pay attention to understand the working conditions, our gas detector can adapt to the conditions: normal temperature, -20 degrees to 50 degrees, humidity below 90% Condensation, the pressure is in the range of 100kp. 








Once the environmental conditions are not inside, it will affect the accuracy of the measurement and the life of the instrument. At this time, we must consider adding gas pretreatment equipment to perform gas treatment, so that the gas that meets the conditions enters the gas sensor head.
