one set of electrodes, three anodes, two 14-mL marked beakers, electrode cleaning polish, stirrer, printer cable, RS-232 port, acid buffer reagent (500 mL), 200 mg/L chloride standard (100 mL), and 6-ft (1.8-m) power cord with US plug.
This automatic chloride titrator provides accurate and highly reproducible measurement results. The system is ideal for use in the food, pharmaceutical, agricultural, and petroleum industries. The system utilizes a method based on coulometric titration — an absolute method where the reagent, silver ions, is precisely and quantitatively generated at the time of analysis by passing a constant current between electrodes. The end point is detected by the use of sensing electrodes which measure the change in the solution conductivity that occurs when excess silver ions are present in the solution. Unlike a conductivity meter, this analyzer actually titrates chloride with silver as in official methods.
Automatic features provide speed and simplicity, reducing labor costs and
