永停滴定法是容量（liàng）分析（xī）中確定（dìng）終點的（de）一種方法。自動永停滴定（dìng）儀是根據中（zhōng）國（guó）藥典77版所載的（de）永停滴定法的要求而試製成功的一種新型儀器，並收載2000版藥典，用作於重氮化測定終點指示，它與外（wài）指示劑和觀察費體試液變化結果等比較，具有精度（dù）高（gāo）、測定準確、使用方便、小巧輕（qīng）便、性能穩定等優點。它是化學實（shí）驗室、藥品檢驗所、各大醫（yī）院、製藥廠、獸藥廠、飼料廠等進（jìn）行醫藥化工等（děng）工業溶量（liàng）分（fèn）析的（de）一必不可（kě）少的測（cè）定（dìng）儀器。
GENERAL
Ascertaining end-point titrimetry is a method to ascertain the end-pointin volumetric analysis, the automatic ascertaining end-point titratoris a new instrument manufac-tured according to the requirement of Titrimetry recorded Chinese Codex(Edition:77)which can be used to measure dia-zonium end-point indication. It has the advantages suchas high precision , exact measurement, convenient usage, stable performance compared with the methodsof using external indicator and watching Fischer liquid ,It is an abso-lutely necessaryinstrument to analyze solution for chemical labs, physic in-spection organizations, hospitals, phar-maceutical factory and so on
