1.1.2 Connectors

The 915 KF Ti-Touch is equipped with the following connectors:

￭ Mains connection

For connecting to the mains supply with the aid of the power supply

unit provided.

￭ Two MSB connectors (Metrohm Serial Bus)

￭ USB connector

For connecting peripheral devices (printer, PC keyboard, etc.), a USB

Sample Processor, a USB flash drive or a USB hub.

￭ Sensor connectors

One connection each for:

– polarizable electrodes

– temperature sensors (Pt1000 or NTC)

For connecting tubing for aspirating solvent and extracting the con-

tents of the titration cell.

1.1.3 Intended use

The 915 KF Ti-Touch is designed for usage as a titrator in analytical labora-

tories. Its main application field is volumetric Karl Fischer titration.

This instrument is suitable for processing chemicals and flammable sam-

ples. The usage of the 915 KF Ti-Touch therefore requires that the user

has basic knowledge and experience in the handling of toxic and caustic

substances. Knowledge with respect to the application of the fire preven-

tion measures prescribed for laboratories is also mandatory.
