Abstract: Automatic potentiometric titrator is an analytical instrument for capacity analysis which is designed according to the principle of potentiometric titration. This paper analyzes the evaluation of uncertainty of volume error of titration tube and indication error of automatic potentiometric titration according to the verification regulation of JJG 814—2015Automatic Potentiometric Titrators.

Key words: automatic potentiometric titration; electrometer error; volume error; indication error; uncertainty

根據(jù)JJG 814—2015《自動(dòng)電位滴定儀》對(duì)自動(dòng)電位滴定儀的檢定,主要包括3個(gè)部分:電計(jì)部分、滴定管部分、儀器示值部分。(剩余3502字)
