Coulometer including generator electrode without diaphragm and integrated stirrer.

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

Small and compact

The 899 Coulometer is the smallest Metrohm coulometer. The magnetic stirrer is already built in and a support rod can be dispensed with, thanks to the titration cell holder. The titration cell stands securely attached on the 899 Coulometer.


Automatic titration start

It can readily happen that the sample is added to the titration vessel without starting the titration beforehand. In such cases, the conditioning continues to run until the reagent is once again titrated until it is dry. Recalculations are not possible and the determination must be repeated. This costs sample and valuable time.

The 899 Coulometer offers an automatic titration start. The titration starts automatically, as soon as sample is added to the titration vessel.


Flexible with accumulator

A Power Box can be obtained as an optional accessory for the 899 Coulometer. This ensures impressive flexibility. Determine the water content of your samples, wherever you like.
