PyroScience is a manufacturer of high-precision optical sensors based on unique optical detection techniques (REDFLASH technology).

The product line includes various fibre-based and smart contactless sensor heads for compact PC-operated and stand-alone read-out devices for measurements in gas, water, aqueous and semi-solid samples. Sensor systems are also available for challenging measurements in organic solvents, microfluidics and high-throughput screening and for various OEM applications, such as oxygen gas monitoring, underwater/deep sea applications, and many others.

We offer unprecedented multi-parameter solutions for applications in e.g. life sciences, experimental biology, aquatic sciences, biotechnology, bioprocessing, microbiology, water- and wastewater-treatment, aquaculture, marine research, or environmental monitoring.

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.
