KY-4 Bromine Valence Bromine Index Tester

KY-4Bromine Value Bromine Index TesterIt is a new generation analyzer developed by our company. Using the principle of microcoulometry titration, the sample is directly added to the titration cell, and bromine is produced through electrolysis, which reacts with the substances consumed by the sample. After the reaction is complete, the electrolysis of bromine is automatically stopped to produce bromine. The microcomputer can automatically calculate the bromine value and bromine index content in the sample based on the amount of electricity consumed by the produced bromine. The computer controls the measurement and electrolysis, and performs data processing. It 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.

KY-4Bromine Value Bromine Index Testercharacteristic:

vThe instrument uses benzene free electrolyte, which is safe and non-toxic. Very few reagents are required. On average, each sample requires less than reagents1milliliter.

vUsing the potential method to indicate the endpoint, the signal is stable and the result is accurate, making it an advanced bromine valence meter.

vUsing specially made sand cores instead of ion membranes will not result in incorrect results due to membrane damage.

vThe instrument adoptsUSBInterface, computer full process control, endpoint discrimination, data endpoint display, high sensitivity, good repeatability!

vThe instrument adopts high-precision 24 bit A/D data acquisition to ensure the accuracy of analysis results.

vControl and process data with a microcomputer, fully automate functions such as signal display, plotting, listing, data storage, and printing.

vVery few samples are required, usually smaller than10Microliters, less than when measuring bromine index50Micro liter.

vThe endpoint is stable for a long time, and the measurement is simple and fast. Usually, only one sample needs to be measured1minute.
