On-line Oxygen Sensors for the Glass Industry, in Glass Melt, Atmosphere and Tin Bath
  • Tin Bath in Float Line

    Tin Bath in Float Line

    The Read-Ox tin bath oxygen sensors for the molten tin and atmosphere in the tin bath of a float glass production line.

  • Glass Production Furnace

    Glass Production Furnace

    The Read-Ox oxygen sensors for the glass melt, combustion and flue gas atmosphere in an industrial glass production furnace.

About us

Read-Ox & Consultancy B.V., started in 2001, is specialised in the production of oxygen sensors for the glass industry. These oxygen sensors are based on the electrochemical cell principle and are able to measure the oxygen activity of the glass melt (in feeder channel, forehearth or canal) or combustion atmosphere (regenerator crown or flue gas channel) in the industrial glass production furnace. Additionally, for the float glass production line we have special oxygen sensors for the tin bath, for inside the molten tin or for in the tin bath protective atmosphere.

Relying on its broad experience in the field of oxygen activity measurements in glass industry, Read-Ox may offer tailor made solutions for various furnace designs.

e-book ‘Foaming of Glass Melts’

Foaming in an industrial glass tank is most often a very undesirable phenomenon,  blocking the heat transfer from the burner flames into the melt. It leads not only to an increased fuel consumption, but may also re...
