1 Introduction
1.1 Description
The Optrode is used as a photometric sensor for various titration methods
that require the use of indicators. Its enclosed glass shaft enables it to be
safely used in nonaqueous or corrosive media. It does not require any
time-consuming care or conditioning.
Equipped with eight LED light sources with different wavelength ranges
(see Table 1, page 10) , it can be used with a large variety of indicators.
The sensor does not have a mechanical switch.
The LED light source can be selected either via the control software tiamo
(version 2.5 and higher) or without the need for contact using the provi-
ded stirring bar.
A USB connection ensures the power supply to the Optrode's light sour-
ces and electronic components. Metrohm titrators are equipped with USB
ports for this purpose. In addition, a USB power adapter is available to
power the Optrode independently.
The Optrode provides an analog measuring signal and can be connected
reliably to any Metrohm titrator at the
Ind. connector. This allows the
Optrode to be used for titration like other sensors.
1.2 Intended use
The Optrode is designed for use with a titrator in analytical laboratories. It
is intended solely as an optical sensor for photometric titrations.
This sensor can be used in chemicals and flammable solvents. Usage of
the Optrode therefore requires the user to have basic knowledge and
experience in handling toxic and caustic substances. Knowledge with
respect to the application of the fire prevention measures prescribed for
laboratories or production plants is also mandatory.
