Advice on selecting a brand for a micro online oxygen detection system
Thread Content
Recently, the factory needs to install a micro online oxygen detection system on the reaction vessels. I’m not sure which brand would be a good choice. Do any of you have any recommendations for reputable suppliers or brands that have been used successfully? It’s important that after-sales service is prompt and convenient; ideally, the supplier should be located in the Jiangsu, Zhejiang, or Shanghai regions, so as to make it easier to visit them. I saw a company named Jiangsu Ai Yi Technology posting about this before; I wonder if there are any other manufacturers that can offer better suggestions than them? I hope to learn more about it.....
Talk about the specific operating conditions: what are the pressure, temperature, and gas composition? What is the oxygen content? Are there zirconia-based, laser-based, or electrochemical methods?
I’m trying to find out which brands of online oxygen analyzers for electrochemistry are good in Jiangsu, Zhejiang, and Shanghai
First, you need to determine whether you are measuring dissolved oxygen (measured in a liquid) or gaseous oxygen； Electrochemical reactions are quite sensitive, but they are consumable items ； Additionally, it depends on whether you need imported brands or domestic brands. For dissolved oxygen sensors, our company acts as an agent for similar products from the German company KNICK; we can send you relevant information for your reference if needed. ghost_0537@126.com
I really don’t know much about brands. Our company used a certain brand from Nanjing, but it wasn’t very effective – the choice of brand was incorrect, and the process gases were complex, which caused corrosion. Although there was pre-treatment, it didn’t help. So I don’t recommend using this approach
1. As for these chemical analysis instruments, let me tell you: they’re all of poor quality; the brand name has absolutely no impact on their performance. The sensors themselves have such poor characteristics that their readings drift significantly, and this drift isn’t even consistent. No matter which brand of instrument you use, you need to calibrate it frequently in order to achieve accurate results. 2. The instruments themselves are unstable and give inaccurate readings; what’s the use of any after-sales service at all? It cannot improve the quality of the instruments or the after-sales service. It’s not some magical tool that can be used at will whenever you need it; after all, it’s just an object. When you’re in a hurry to pee, no matter how good the after-sales service is, there has to be some time limit, right? Just like with Order No. 5 – a few items were sent out, but due to heavy snow and ice on the roads, the highways were closed and flights were canceled. This morning I checked the tracking information; it’s the 9th today. ZTO is still on its way, and SF Express hasn’t delivered either
Without specific process parameters, how can recommendations be made?
Micro oxygen analyzers basically operate on an electrochemical principle. The DF series from Shifu Mei Company uses non-consumable sensors; our company is also using it, and maintenance involves simply adding electrolyte on a regular basis.
Is this an imported brand of meters? Do you use domestic ones in your company?
