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 ultra-trace oxygen sensor cap UTROXCAP-SUB integrates an ultra-trace range oxygen sensor spot (without optical isolation), especially developed for underwater and deep-sea applications. The UTROXCAP can be screwed directly onto the PyroScience SUB-connector of a compatible underwater read-out device. The UTROXCAP-SUB is protected and hence highly robust against mechanical impact and ideal for long-term monitoring applications. The sensing principle is based on an optical detection method and shows virtually no drift and fast response. The UTROXCAP-SUB is especially suited for trace oxygen detection in oxygen minimum zones or during de-oxygenation events underwater.

  • Sensor screw cap with integrated optical ultra-trace oxygen sensor
  • Fast sensor with low drift
  • For all devices with -SUB connector
  • Minimized maintenance by simply exchanging the cap
