Preface
1 Preface
You have chosen a new, innovative technology for measuring oxygen.
The Microx TX3 is a compact, easy to transport and completely PC-controlled micro fiber
optic oxygen transmitter. The data evaluation is PC supported as well.
The Microx TX3 is developed especially for fiber optic oxygen microsensors, and
microsensors integrated in flow-through cells. They are based on a novel technology, which
creates very stable, internally referenced measured values. This allows a more flexible use of
oxygen sensors in various fields of interest.
Optical oxygen sensors (also called optodes) have several important features:
They are small.
Their signal does not depend on the flow rate of the sample.
They can be physically divided from the measuring system which allows a non-
invasive measurement.
They can be used in disposables.
Therefore, they are ideally suited for the examination of small sample volumes, for highly
parallelized measurements in disposables, and for biotechnological applications. A set of
different oxygen minisensors, flow-through cells and non-invasive sensors is available to
make sure you have the sensor which matches your application.
Please feel free to contact our service team to find the best solution for your application.

Microx TX3 Description of the Microx TX3 Transmitter
2 Description of the Microx TX3
Transmitter
The Microx TX3 is a precise single channel micro fiber optic oxygen transmitter with
temperature compensation. It is designed for very small fiber optic oxygen microsensors (tip
diameter < 50 µm) with sensor coating type PSt1 (limit of detection 0.05 % oxygen, 20 ppb
dissolved oxygen). The small outer dimensions and low power consumption make it suitable
for portable use. For operation, a PC / notebook is required. The Microx TX3 is controlled
using a comfortable software, which also saves and visualizes the measured values.
The Microx TX3 has a dual 12 bit analog output, and an external trigger input to be connected
to a data logger.
The analog outputs are programmable to deliver oxygen, temperature or the raw values
(phase or amplitude). The data are retrieved via PC / notebook and USB (alternatively
RS232) (digital) or using the external trigger input (analog).
Features:
High precision
Portable (battery power optional)
Analog / Digital data output (on request)
