Advantages and disadvantages of several types of paramagnetic oxygen analyzers
Thread Content
For experimental purposes, it is necessary to purchase an online oxygen analyzer with high measurement accuracy and a large measurement range. After reviewing relevant information, it was initially decided to use an oxygen analyzer based on the paramagnetic method; however, there is limited information available regarding the advantages and disadvantages of the different categories under this method. Therefore, I would like to ask for your advice on the advantages and disadvantages of the three types of analyzers: magnetomechanical, magnetopressure, and oxythermomagnetic convection types. These analyzers should be easy to use, respond quickly, and provide accurate measurements. Thank you all!
I only know something about magnetomechanical ones. For online analysis, you can consult ROSEMOUNT’s Model 755 and related products from Shanghai Shifu Mei. The range can be selected according to the customer's requirements. theirs are all measured based on the paramagnetic principle of oxygen, and the quality is quite good. The price is relatively high; one unit consists of an entire cabinet in which a fairly complex sampling and processing system is installed. If it’s for laboratory use, I’m not familiar with it.
Why not choose laser oxygen measurement? For example, model CI-385
