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 new 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 FireStingO2 meter 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.
