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 fiber-optic temperature sensors from PyroScience are based on an innovative technology utilizing temperature-sensing properties of luminescent indicators. The needle-type temperature minisensors feature unprecedented fast response times in liquids (down to <<1s) and gases combined with very high spatial resolution (down to ~200µm). Importantly, the temperature minisensors are fully compatible with the FireStingO2 meters and can be used for true temperature compensation of optical oxygen sensors from PyroScience.

The Needle-Type Temperature Minisensors are composed of a metal housing available as retractable (TPR430) or fixed (TPF1100) version and can be connected to any channel of the oxygen meter FireStingO2. The temperature minisensors can be applied for (fast) measurements in gases and aqueous liquids, being resistant to corrosive environments (e.g. seawater), as all metallic parts are made of stainless steel.

TPF1100. The sensor tip of the fixed needle-type temperature minisensor is glued into a straight-cut needle and protrudes ca. 2mm. Hence the fragile sensor tip is unprotected and the sensor needs to be handled with care, avoiding direct contact with hard surfaces.

TPR430. The fragile sensor tip of the retractable temperature minisensor is surrounded by a 40 mm long syringe needle and can be moved out of the needle with a unique 4-step sliding mechanism. When retracted into the needle, the sensor tip is fully protected while handling the sensor or while penetrating packages or a septa.
