Mobile coulometer for water determination anywhere you want • Extremely small & compact • Maximum flexibility due to independent power supply • Automatic start of titrat

899 Coulometer – the smallest and most compact Metrohm coulometer ever 02 The 899 Coulometer couldn’t be any smaller and more compact: With dimensions of 144 x 112 x 282 mm (W x H x D) the new Metrohm coulometer needs no more benchspace than a sheet of DIN A4 paper. That’s the result of smart design by Metrohm engineers: It may be small, however, the 899 Coulometer does not compromise on performance. Water contents can be determined with utmost precision down to trace levels. • The 899 Coulometer is equipped with an integral magnetic stirrer. You no longer need to connect an external stirrer....

Determine water content anywhere you want You are in the field and need to know the water content of a sample. The laboratory is far and waiting for results is out of the questions. There is no socket around to plug in a power cord either. No problem with the mobile 899 Coulometer. Simply rely on the instrument’s independent power supply that comes with the optional Power Box. It contains a set of rechargeable batteries that last for hours of uninterrupted and reliable operation. The 899 Coulometer gives you full independence as you can now perform coulometric determinations of the water content...

Automatic start of titration 04 It can easily happen that the sample is put into the titration vessel before one has started the titration. In this case the conditioning continues until the reagent has again been titrated dry. Recalculations are impossible and the analysis has to be repeated. That means wasted sample, lost time and more stress. With the 899 Coulometer that cannot happen. The automatic start ensures that the titration begins automatically as soon as sample is put into the titration vessel.

Thermal sample preparation: the oven method It may be small but the mobile 899 Coulometer provides the same capabilities as the larger Metrohm coulometers. This includes thermal sample preparation, and even fully automated, if required. Not every sample can be put into the titration vessel directly. There are various possible reasons for this: • limited solubility • secondary reactions with reagents • slow release of water from the sample • release of water only at higher temperatures • dirt in the titration cell The oven method is recommended for such samples. Here, the water contained in the...
