Abstract
An alkaline-acid end point detector for titration reactions in which the phenomenon of chemiluminescence is used to detect the end point by monitoring, by means of an electronic light detector, the light output of the reaction materials in a light-tight vessel. The output from the detector is differentiated to detect the maximum output which corresponds to the reaction end point. The detector is useful in the determination of acid numbers in oils and greases.
