2 Introduction
2.1 Instrument description
The 900 Touch Control is an operating unit with a touch-sensitive screen.
You can operate the following control instruments with the 900 Touch
Control:
￭Titrandos
￭Sample Processors
￭846 Dosing Interface
￭867 pH Module
￭856 Conductivity Module
With the 900 Touch Control, you can conveniently manage all of your
titrants, sensors, methods, etc. For example, you can connect a USB flash
drive to the USB connector as an external storage medium. You can use
this additional memory not only to store your methods and determina-
tions, but also to create a backup together with all of the data and set-
tings of your system. Thanks to the integrated Ethernet connector, the
device can be connected to your network, thus offering you the following
options, among others:
￭Saving data to a PC within the network
￭Printing reports on a network printer
￭Sending displayed messages as e-mails
2.2 Titration and measuring modes
The 900 Touch Control supports the following titration and measuring
modes. Whether a particular mode is available or not depends on the type
of the control instrument connected.
￭DET
Dynamic equivalence point titration. The reagent is added in variable
volume steps.
Measuring modes:
–pH (pH measurement)
–U (potentiometric voltage measurement)
–Ipol (voltametric measurement with selectable polarization cur-
rent)
–Upol (amperometric measurement with selectable polarization
voltage)
