How to calibrate a sulfuric acid concentration meter when no standard solution of such high concentration is available?
Ugh, I want help too~~~ Please, someone experienced on the forum can help answer it~~~
May I ask what principle the instrument that your company needs to calibrate operates on? Also, can third-party standard samples be used as a substitute for high-concentration sulfuric acid? http://player.youku.com/player.php/sid/XOTE2NjIzODIw/v.swf
Concentrated sulfuric acid generally does not require calibration with an actual sample. If it is the density method, there are standard density tables for sulfuric acid. In the case of the conductivity method, based on several available conductivity curves, the instrument manufacturer can embed the calibration curve directly.
