Plug-and-play titration sensors

Mettler Toledo has released a range of plug-and-play titration sensors, designed for precise measurement of mineral oils and derived products.

The plug-and-play sensor chip immediately recognises connection with Excellence titrators, providing smooth transfer of relevant data. These monitoring functions check that the sensor is in optimal condition for non-aqueous titrations.

The DGi116-Solvent’s large round glass bulb provides sensitive pH response. Its sliding glass sleeve promotes signal equilibration and is easy to clean. The gold shield for the inner glass half-cell provides electrical and static shielding for noise reduction.

The DMi148-SC is suitable for determining chloride and, after simple sulfidisation of the silver ring, for the titration of mercaptans in petrochemical products. The pH glass reference minimises diaphragm clogging and electrolyte refilling. Acid-based titration applications are possible using the silver ring as reference.

The Rondo sample charger automates the workflow, including the dissolution of the oil sample, titration, and cleaning condition of the sensor. Each sample is analysed in the same manner, increasing result integrity. Daily titration analyses can be started with one click and run unattended.
