The new compact FireSting pro is an unprecedented one-device solution for multiple analytes and sensor heads. It is a PC-controlled (USB) fiber-optic multi-analyte meter available with 1, 2 or 4 optical ports, which can be combined with the complete sensor portfolio for optical O2, pH, and temperature sensors from PyroScience. Each optical port is freely configurable for several analytes and sensor types. These range from microsensors (50 µm tip) to robust probes (3 mm tip), and include diverse smart contactless sensor solutions (for measurements in closed systems/respirometry, microfluidics and complex geometries), as well as sensors for different ranges (full and trace range O2, pH ranges). A precision Pt100 temperature sensor can be connected to the temperature port, allowing automatic zero noise and zero latency temperature compensation of the optical sensor measurements in samples with varying temperatures, even during high speed measurements. The new FireSting pro features improved ambient light suppression for applications at in situ light conditions, as well as smart measurement modes for prolonged sensor lifetime. Several FireSting pro devices can be simply operated with a single PC in a single Pyro Workbench window, offering scalable fiber-optic multi-parameter sensor systems with e.g. 8, 16, 32, or 64 channels. It has never been easier to measure important parameters in a single sample at high precision with maximum flexibility concerning analyte, sensor format, measuring mode, and application range.


Innovative REDFLASH Technology. The REDFLASH technology from PyroScience is based on unique oxygen-sensitive REDFLASH indicators. In contrast to common techniques using blue-light excitation, the REDFLASH indicators are excitable with orange-red light and show an analyte-dependent luminescence in the near infrared (NIR). The REDFLASH technology impresses by fast response times,  high precision, high reliability, low power consumption, low cross-sensitivity, and. reduced interferences.

Integrated Pressure and Humidity Sensors for Easy Calibration. The FireSting pro device comes with integrated sensors for atmospheric pressure (mbar) and relative humidity (%RH) of the ambient air for a precision calibration procedure in water or ambient air with the new user-friendly software Pyro Workbench. The integrated pressure sensor can be used for automatic pressure compensation during long-term oxygen measurements performed e.g. in units of %O2 or %air sat. These oxygen units show a strong dependence on atmospheric pressure changes (weather changes, altitude), which is simply neglected by most commercially available oxygen meters. The FireSting pro offers automatic pressure compensation integrated seamlessly into the included innovative software Pyro Workbench.
