Optical Oxygen Meter - FireSting-O2
The compact FireSting-O2 is a PC-controlled (USB) fiber-optic oxygen meter can be combined with the complete optical oxygen sensor and optical temperature sensor portfolio from PyroScience, ranging from microsensors (50 µm tip) to robust probes (3 mm tip), and including also diverse smart contactless sensor solutions. Most oxygen sensor types are available for the full O2 range and for a lower trace oxygen range (0-10%). Automatic temperature compensation of the oxygen measurements in samples with varying temperatures is possible with an optical temperature sensor connected to an optical channel or with a Pt100 temperature probe connected to the temperature port of the FireSting-O2. With the included user-friendly logger software several meters can be operated within one Pyro Workbench window. The integrated Pyro Data Inspector features multiple functions like drift compensation or calculation of oxygen rates.
Innovative REDFLASH technology. The REDFLASH technology from PyroScience is based on the unique analyte-sensitive REDFLASH sensor materials. The REDFLASH sensor materials are excitable with red light and show an analyte-dependent luminescence in the near infrared (NIR). The REDFLASH technology impresses by its high precision, high reliability, low power consumption, low cross-sensitivity, and fast response times. The red light excitation significantly reduces interferences caused by autofluorescent samples. Further, the NIR detection technology significantly reduces interference with ambient light, known from the old blue-light techniques.
Supported analytes. This meter is compatible to a broad range of optical oxygen and temperature sensors. Our optical pH sensors are not supported. External Pt100 temperature probes for temperature compensation can be connected to the LEMO-connector of this device and are supported.
Laboratory device. This plug & play solution comes with a standard USB connection and a free Windows logging software.
Next generation PC software. The Pyro Workbench is our newest software solution and available as free download in the Downloads tab. Up to 10 PyroScience meters can be operated by the Pyro Workbench at once. It is used for configuring the device, calibrating the sensors, starting the logging, and finally for retrieving the logged data. The sensor readings are displayed numerically and graphically and can be logged in respective data files for further data processing. Additionally, the integrated Pyro Data Inspector features multiple data processing options like drift compensation or calculation of oxygen rates.
Optical channel. This meter features four optical channels with ST-connectors, compatible to a broad range of fiber-optic and contactless sensors. The optical sensor of your choice must be purchased separately.
Temperature port. This device is equipped with a LEMO-connector for Pt100 temperature probes, which can be used for automatic temperature compensation of optical sensor measurements, or simply for logging temperatures in liquids and gases.
Integrated pressure and humidity sensors. All FireSting devices come with integrated sensors for atmospheric pressure (mbar) and relative humidity (%RH) of the ambient air for a user-friendly precision calibration procedure in water or ambient air. The integrated pressure sensor can be used for automatic pressure compensation of oxygen measurements performed e.g. in units of %oxygen, %air saturation or in DO concentration units (µmol/L, mg/L). These oxygen units show a strong dependence on atmospheric pressure changes (weather changes, altitude). Automatic pressure compensation is integrated seamlessly into the included innovative logger software / user interface.
Analog output. This device has 4 integrated analog outputs (0..2.5V), which can be configured and scaled with the included software. Optionally, each analog output can be also configured as an alarm output (e.g. for control tasks like observing a defined oxygen level in fish tanks).
Broadcast Mode. This meter can be operated optionally without any PC connected in the so-called broadcast mode. Simply activate the broadcast mode by connecting and powering the meter with a standard micro-USB charger (as used for mobile phones). The measured sensor data are read out via the analog output (or via the serial interface of the extension port).
LabVIEW library. For customer software solutions, a fully functional LabVIEW library is available in the downloads tab. On request, a respective Python library (in beta version) will be sent to you. Just let us know.
