Data fluctuation is very small.
Compared with other brands of Hg/HgO electrodes, STONYLAB electrodes are cost-effective and of very good quality.
It is very compatible with the electrochemistry workstation in my lab, this electrode can be used immediately after plugging it in without any problems.
Asked some questions before purchase, customer service very patiently answered my concerns and gave a lot of suggestions for use, the purchase experience is very good.
Electrode has a fine workmanship appearance, the glass part is thick and feels very reliable in quality.
