Calibration issues of micro-oxygen analyzers
Thread Content
The electrochemical micro-oxygen analyzer used in our factory, from Beijing Jiuxinglong, has a range knob and a zero-point knob. Even after turning the range knob to the extreme during calibration, the range value cannot be adjusted (it remains too high).
I’ve never used Jiuxinglong; I have used TELEDYNE, and it’s very simple
It’s possible that the sensor needs to be replaced; the Pb inside has run out
What kind of brand is this? Has anyone heard of it? It would be best for the poster to ask the manufacturer to resolve the issue; for products from such unknown manufacturers, it might even be impossible to find any information about them online.
The after-sales service quality at Beijing Jiuxinglong is not very good
For instruments related to trace oxygen, TELEDYNE products must be used; domestic alternatives should be avoided as much as possible
Emerson also has micro-oxygen analyzers!
