The headspace oven technique of the TO 7280 allows the separation of the water to be titrated from liquid, solid and semi-solid (paste-like) samples. In combination with the TW 7650 sample changer, up to 49 samples can be analysed.

• Semi-automatic or fully automatic water determination
• No contamination of the anolyte, generator and indicator electrodes
• Application range from 35 to 280 °C
• Reproducibility: ±3 μg bei 10 to 1000 μg, 0,3% bei >1 mg

Requires TitriSoft version 3.50 or higher to operate. One position is reserved for the zero-vial to determine the start drift.
