Product Overview:

The TBR-4000 microcomputer bromine index analyzer (formerly known as TBR-2000 bromine index analyzer) is a new generation of intelligent instrument based on the principle of microcoulometry titration, introducing new scientific research achievements, using computer (or microcontroller) to control measurement and electrolysis, and performing data processing.

This instrument is the first to use the potential method to indicate the endpoint, and its signal stability is one order of magnitude higher than the conventional current method. It also uses a specially designed artificial sand core instead of the conventional glass sand core and ion membrane, making the operation particularly convenient. Compared with similar instruments at home and abroad, it ranks first in terms of automation level, sensitivity, and accuracy. It is an effective tool for determining bromine value and bromine index in petrochemical process control and product quality testing. It has the characteristics of fast balancing speed, good stability, automatic endpoint judgment, accurate results, easy operation, fast analysis speed, automatic data processing, and continuous printing.

This instrument can be widely used for the determination of bromine value and bromine index of petroleum and chemical products such as gasoline, kerosene, diesel, lubricating oil, and light and heavy aromatic hydrocarbons.
