Seeking advice on a trace water and oxygen analyzer
Thread Content
I’m reaching out to the experts on this forum for help. I would like to know the advantages and disadvantages of GE’s micro-oxygen analyzers, Michell’s micro-oxygen analyzers, and TELEDYNE’s micro-oxygen analyzers in terms of performance, maintenance, and price. I have only worked with GE’s models; I’m not familiar with the other two brands. Please give me some guidance. Thank you.
I’ll help you switch to the dashboard section, where there are more people to interact with!
This type of question falls under product testing; I think the original poster should get one set of each instrument, use them for some time, and then write up their experiences so that others can share them. The quality of a set of analytical instruments cannot be described using simple qualitative terms. It’s like asking you which one is tastier, bitter gourd, chili peppers, or stinky tofu – is there a standard answer?
I understand this principle as well, but in practice it’s a very troublesome matter. The GE analyzers that are already in use on site have hosts, preprocessing units, and cables all designed to work with GE products; it’s difficult to replace them with those from other brands, and the management won’t approve it either. There’s even a risk of being investigated by certain departments! The new device is set to be equipped with a trace oxygen analyzer; if a different brand is chosen, I will share my experiences regarding its performance and maintenance issues with all of you after using it for some time. The previous unit used a GE-brand micro water and oxygen analyzer, which performed quite well. The issue with the micro oxygen cell is that the sampling pressure must be carefully controlled; high pressure can cause the electrolyte in the oxygen cell to leak.
They are all electrochemical types: one is an oxygen cell, and the other is of the electrolyte type. It must be said that GE does a great job in terms of business relationships; if it weren’t a state-owned enterprise, private companies might consider the other two options. The prices aren’t comparable, you know
