1 Introduction

The FireStingO2-Mini-ST is a high precision optical oxygen meter
for liquid or gas samples, which is based on the opto-electronics of
the successful USB-device FireStingO2 from PyroScience. Most
features of the FireStingO2-Mini-ST are identical to the

FireStingO2. Therefore, for a general introduction it is highly

recommended to consult additionally the detailed manual of the

FireStingO2. Here we will cover mostly the differences of the
FireStingO2-Mini-ST compared to the FireStingO2.

The FSO2-Mini-ST is compatible to most oxygen sensors types
available from PyroScience.

Further, it includes also internal high-precision sensors for
(i) ambient atmospheric pressure, (ii) relative humidity of the
ambient air, and (iii) the temperature of the ambient air.
Additionally, an external temperature probe (PT100) used for
automatic temperature compensation of the oxygen measurement
can be soldered directly to the module (e.g. item TSUB21-NC).

This manual provides only specific information needed for the

FireStingO2-Mini-ST. It is highly recommended to study carefully

the manual of the USB-device FireStingO2 in order to get a
general introduction in optical oxygen measurements and the
related sensor types.

2 Safety Guidelines

In order to guarantee an optimal performance of the FireStingO2-

Mini-ST please follow these operation instructions and safety

guidelines. If any problems or damage evolve, please disconnect
the instrument immediately, mark it to prevent any further use and
consult PyroScience for repair or maintenance service. The

FireStingO2-Mini-ST should not be manipulated or opened by

unauthorized persons (except for the needed steps in order to
solder the external PT100 to the internal PCB-board), only by

PyroScience or persons advised directly from PyroScience.

Please note that opening the housing (except removing the front
cap for accessing the solder pads for the external temperature
sensor) will void the warranty. There are no serviceable parts inside
the device.

The FireStingO2-Mini-ST and the sensors should be kept and
stored outside the reach of children in a secure place under dry and
clean conditions at room temperature, avoiding moisture, dust,
corrosive conditions and heating of the instrument. This device is
not intended for medical, military or other safety relevant areas. It
should be used in the laboratory by qualified personal only
following the operation instructions and safety guidelines of this
manual.

Please follow the appropriate laws and guidelines for safety like
EEC directives for protective labor legislation, national protective
labor legislation, safety regulations for accident prevention and
safety data-sheets from manufacturer of chemicals used during
measurements.

When used in the field, the environmental conditions (like high
humidity, dust, exposure to direct solar radiation) may cause
damage or interference of the FireStingO2-Mini-ST, which is on
the user's authority.

Before using the FireStingO2-Mini-ST and its sensors, read
carefully the instructions and user manuals.

In case of problems or damage, disconnect the instrument and
mark it to prevent any further use! Consult PyroScience for
advice! There are no serviceable parts inside the device. Please
note that opening the housing will void the warranty!

The FireStingO2-Mini-ST is not watertight, is sensitive to
corrosive conditions and to changes in temperature causing
condensation. Avoid any condition (e.g. direct sun light) causing
a heating of the device above 50°C (122°F).

Calibration and application of the sensors is on the user’s
authority, as well as data acquisition, treatment and
publication!

The sensors and the oxygen meter FireStingO2-Mini-ST are not
intended for medical, diagnostic, therapeutic, or military
purposes or any other safety-critical applications. The sensors
must not be used for applications in humans and must not be
brought in direct contact with foods intended for consumption
by humans.

The FireStingO2-Mini-ST and sensors should be used in the
laboratory by qualified personnel only, following the user
instructions and the safety guidelines of the manuals, as well as
the appropriate laws and guidelines for safety in the laboratory!

Keep the sensors and the oxygen meter FireStingO2-Mini-ST out
of reach of children!

3 Overview

Fig. 1 provides an overview of the FSO2-MINI-ST. The overall
dimension of the module is 67 x 25 x 25 mm (without the optical
port). Two M3 threads can be found at the bottom for mounting
the module in customized setups. Please note, that one of the M3
threads is hidden below the type label. The position of that M3
thread is roughly indicated on the type label. Just penetrate the
type label at this position with e.g. a needle or nail in order to
access the M3 thread.

3.1 Optical Port for Oxygen Sensors

The FSO2-MINI-ST provides an ST-connector as known from the
USB-device FireStingO2. Thus, all optical oxygen sensors available
for the FireStingO2 (e.g. needle-type sensors, robust probes, fibers
for read-out of sensor spots, flow through cells, respiration vials)
can be directly connected to the FSO2-MINI-ST. Please refer to the
manual of the FireStingO2 for further details.
