Product Name: Permanganate Water Quality Online Automatic Monitor Product Model: TY-CODmn Product Overview This product is developed by Tianjin Tongyang Technology Development Co., Ltd. for many years in the field of water quality analysis ..
This product is a maintenance free online analytical instrument launched by Tianjin Tongyang Technology Development Co., Ltd. based on years of research on water quality analysis products. The online analyzer uses the acid oxidation potentiometric titration method to detect the permanganate index in water. The testing process is: through system control, water sample collection is automatically completed; The water sample enters the reaction tank for heating, and under high temperature and acidic conditions, partially oxidizes the reducing substances in the water; Then add an excess of sodium oxalate and react, and finally titrate the remaining sodium oxalate at a uniform rate. Determine the endpoint of the titration using ORP, obtain the back titration time, and check the working curve to obtain the test value
monitoring parameters
