AUTOMATIC PHOTOMETRIC TITRATOR

摘要

A B S T R A C T"Automatic Photometric Titrator"An alkaline-acid end point detector fortitration reactions in which the phenomenon of chemilum-inescence is used to detect the end point by monitoring,by means of an electronic light detector; the lightoutput of the reaction materials in a light-tightvessel. The output from the detector is differentiatedto detect the maximum output which corresponds to thereaction end point. The detector is useful in thedetermination of acid numbers in oils and greases.
