Abstract
The opacimeter is an optical instrument designed to measure the light-transmission of a colored or turbid solution. A Loewenthal photronic type light-sensitive cell connected to a microammeter is used to measure the intensity of the light transmitted by the solution under test. The light-intensity falling on the sensitive cell is kept within a fixed range by varying the distance of the cell from the source. The instrument is arranged so that a 30-cc. test tube or a 300-cc. Kohle flask may contain the reaction mixture. The results of analyses are determined from calibration curves prepared from known solutions.
