Flow-Through Cells with Optical Oxygen and Temperature Sensor

  • Flow-through cells with integrated contactless optical oxygen and temperature sensor
  • Luer-lock with tubing adapters
  • Measures simultaneous temperature and oxygen in gas or aqueous liquids
  • For True Temperature Compensation of integrated Oxygen Sensor

The optical temperature sensors from PyroScience are based on an innovative technology utilizing temperature-sensing properties of luminescent indicators. The combined flow-through cells have an integrated optical temperature and oxygen sensor for contactless measurements in gaseous or liquid samples flowing through the cell. The cell is equipped with Luer-lock connectors on both tubing ends. The included set of Luer-lock adapters allows direct connection of tubings with ca. 3-4 mm inner diameter. Importantly, the combined contactless temperature and oxygen sensors are fully compatible with the multi-channel FireSting devices from PyroScience, to which the flow through cell can be connected with two optical fibers (see accessories below). The optical temperature sensor in the combined flow-through cells can be used for true temperature compensation of the integrated oxygen sensor for high precision measurements.
