Additional Information

ST-1573 Bromine Value/Bromine Index Tester

Product Introduction:

        The ST-1573 Bromine Value/Bromine Index Tester is based on the micro-coulometric principle and is computer-controlled. It is an effective instrument for determining bromine value and bromine index in petrochemical process control analysis and product quality testing. Using the micro-coulometric titration principle, the sample is directly added to the titration cell, where bromine is generated through electrolysis and reacts with the substances consumed by the sample. After the reaction is complete, the electrolysis for bromine generation automatically stops. The microcomputer automatically calculates the bromine value and bromine index content in the sample based on the electricity consumed for bromine generation. The computer controls the measurement and electrolysis and performs data processing. It is widely used for determining the bromine value and bromine index of petroleum products such as gasoline, kerosene, diesel, lubricating oil, and light and heavy aromatic hydrocarbons.

Features:

◆ The instrument uses a USB interface, with full computer control, endpoint judgment, data endpoint display, high sensitivity, and good repeatability

◆ Uses a computer for control and data processing, automatically completing functions such as signal display, graphing, tabulation, data storage, and printing

◆ The instrument uses a benzene-free electrolyte, ensuring safety and non-toxicity. Very few reagents are required, with an average of less than 1 ml per sample

◆ Uses potentiometry to indicate the endpoint, ensuring stable signals and accurate results

◆ The endpoint remains stable for a long time, making the measurement simple and fast. Typically, only 1 minute is needed to measure one sample

◆ Utilizes high-precision 24-bit A/D data acquisition to ensure the accuracy of analysis results

◆ Uses a specially designed sintered glass disc instead of an ion membrane, avoiding erroneous results due to membrane damage
