Which is the best domestic online pH meter for use in situations where the temperature of the solution is around 90 degrees, and the pH value ranges from 2 to 12? It is used to measure the pH value during the reaction between dilute sulfuric acid and sodium aluminosilicate in reaction vessels
There isn’t much domestic contact; we mostly use ABB products
This is really tricky; if you say it in China, it sounds like advertising
OP, first define what a good online pH meter is I think online analyzers can only be classified as suitable for certain applications or not; it’s hard to say there is any difference between good and bad ones.
You need to tone down your question a bit – when a pH meter is used at temperatures above 80 degrees, its lifespan drops dramatically; an electrode may become unusable after just a week or even less time. I tried Shanghai Leici products, but they didn’t work in the end. E+H and Mettler products are good, but the electrodes are really expensive.
We have also used Mettler’s, and it is indeed very expensive.
Does ABB’s product have a long service life at 90 degrees?
What is the lifespan of your ABB under 90-degree operating conditions?
A probe costs around 5,000 – that’s too expensive.
