Dear colleagues in the chlor-alkali industry, is the online analysis of chlorine content and water content operating properly?

It’s not normal, as there is acid mist deposition; therefore it needs to be cleaned frequently, otherwise the water content will be 0PPM. Last edited by yzhms on 2009-3-7 00:02.]
It’s not good; it keeps breaking. It might be a problem with the material
Ours are not good either; they break down frequently. Replacing the coating doesn’t help either, as the issue always persists at the same level. We’ve contacted the manufacturer many times, but the fundamental problem still can’t be resolved
Are there any better options that people can use as a reference, and to find out the reasons behind that?
I’m not sure where exactly the chlorine moisture analyzer mentioned by the original poster is used
It doesn’t work well; it’s just a piece of furniture now. Currently, most of the water content in chlorine is analyzed by taking samples back to the analysis laboratory. This post was last edited by limingshuguang on 2009-3-6 21:32.]
It doesn’t perform well and breaks down frequently. I asked the instrument maintenance staff, and they said it’s just the way it is – there’s no solution to it; even imported ones don’t last long either.
Ours works okay; manual analysis is inaccurate, so we still rely on the moisture analyzer.
It must be cleaned regularly, that’s what the experts say
Ours are not good either; they break frequently. It seems they are imported products, and even the domestic agents don’t know much about them. They were sent for repair, but it wasn’t fixed, so they were sent back.
It’s possible that the installation location is incorrect. It depends on what brand of online chlorine moisture analyzer the user has; such devices are expensive – in China their price is usually over 100,000 yuan, while abroad the cheapest ones still cost over 200,000 yuan. The CMC AT-2101 from Germany is a good option. This post was last edited by limingshuguang on 2009-3-16 at 11:25
So, online analyzers for chlorine water content still don’t work? Is there none that can be used?
It has been running for over half a year, and overall it’s fine; the calibration isn’t very clear though. I’m not sure how you carried out the calibration
