852 Titrando with Touch Control and generator electrode without diaphragm

2.852.0160 852 Titrando with Touch Control and generator electrode without diaphragm

Coulometer including generator electrode without diaphragm, complete volumetric titration cell and Touch Control.

Coulometry is the ideal method for water determination in liquids, solids and gases when it comes to water determination in the trace range (10 µg to 10 mg absolute water). In addition, coulometry is an absolute method and thus no titer determination is necessary.

Recommended coulometry measuring range: 10 µg - 200 mg absolute water

The 852 Titrando controls not only coulometric, but also volumetric Karl Fischer titration.


  • Coulometric and volumetric titrations
  • Bromine index
  • Automatic titration start
  • Automatic reagent replacement

Coulometric and volumetric titrations

Should the water content of the samples be too high for coulometric determination, this will not be a problem for the 852 Titrando. This instrument can determine samples with water contents ranging from a few micrograms to contents of 100% without difficulty.

Bromine index

It is now possible to determine bromine indexes coulometrically with the 852 Titrando. The conventional coulometric titration cell can also be used for this application. The generator electrode without a diaphragm must be replaced with one that is equipped with a diaphragm. Anolyte and catholyte must also be adapted.

Automatic titration start

It can readily happen that the sample is injected into the titration vessel without the titration being started beforehand. If this is the case, then the water in the sample will be conditioned away and the measurement will need to be repeated. This will no longer be a problem for you with the 852 Titrando. The instruments start the titration automatically, as soon as the sample is added. This way, you save on reagents, sample and above all on precious time.

Dosing unit and Dosino

Dosinos and dosing units can be connected to one of the four MSB connectors of the 852 Titrando. These can be used for volumetric Karl Fischer titrations or also for the addition of sample, standard or auxiliary solutions such as solubility promoters. In addition, reagent replacement can be automated, which means that the cell does not need to be opened, thus excluding the possibility of moisture making its way inside. Long conditioning times after reagent replacements are thus avoided.
