The 851 superb generation Coulometric Moisture Titrator integrates a number of advanced technologies from Metrohm, and is the masterpiece of the high-end Coulometric Moisture Titrator. The dead-volume burette and multiple intelligent technologies are ideal for highly automated and intelligent laboratories.

• Bromine index: The bromine index is a measure of the number of double bonds present in the sample. Similar to the way that elemental iodine is produced in the coulometric moisture determination, the elemental elemental substance required to determine the bromine index is also directly electrolytically generated in the titration cell and reacts with the double bond in the sample. The 851/852 Titrando can also determine the bromine index based on the coulometric method. No additional accessories are added. The original indicator electrode, generator electrode and titration cell are also suitable for this application. Just change the reaction medium

• Button-free automatic start titration: Without any buttons, add the sample and the titration will start automatically immediately. No need to worry about misoperation, prevent waste of reagents and samples, and save valuable experiment time

•Automatic reagent replacement-safe handling of toxic reagents: Only one of the 4 MSB interfaces can be connected to the Doss™ dosing unit, and the reagent can be automatically replaced without opening the titration cup to prevent moisture in the air When entering the titration cup, the equilibration time is shorter after reagent replacement, and direct contact with toxic reagents is avoided. The reagent replacement program can be automatically started. And can be used to add samples, standard solutions or auxiliary solvents: solubilizers, etc.
