1 Overview
1.1 OMNIS Titrator – Product description
The OMNIS Titrator is the central instrument of an OMNIS titration system.
It contains the logic necessary for controlling the titration system. The
OMNIS Titrator is connected to the Ethernet network and to the power
grid. It assumes responsibility for the energy supply to all of the modules
in the titration system and for communications between the titration sys-
tem and the OMNIS Software. All of the other modules of the titration
system are connected with the OMNIS Titrator.
The OMNIS Titrator with magnetic stirrer can also be used as a stand-
alone instrument with manual sample change.
The OMNIS Titrator can be operated with the OMNIS Software if it is con-
nected to the Ethernet network.
The scope of the functions of the OMNIS Titrator is defined in the selected
function license.
