2 separate interfaces for the connection of printer, balance, and com-
puter
8
Remote lines (input/output)
for the connection of the Remote Box, Sample Changers, robots etc.

Connection of electrodes and temperature sensor
• 2 high-impedance measuring inputs for pH and U measurements.
They can either be used separately or for differential potentiometry,
see page 215.
Important: If you work with both measuring inputs in the same ves-
sel, the same reference electrode must be used.
• 1 measuring input for polarized electrodes, e.g. KF electrode
• 1 measuring input for PT100 or Pt1000 temperature sensor

Connection for separate keypad
11
Connection for power cable
With power supplies where the voltage is subject to severe HF distur-
bances, the Titrino should be operated via an additional power filter,
e.g. Metrohm 615 model.
