Speciality Glass

Speciality Glass
Speciality glass is a wide-ranging term encompassing glass with non-standard constituent materials, or glass that undergoes special treatment to make it suitable for a particular application. 

The production process for speciality glass has several points where temperature measurements are key. This includes thermal imaging of the melt tank, temperature measurements in the forehearth and monitoring the annealing process.

Accurate measurements at critical locations are vital to speciality glass manufacture. AMETEK Land has a range of advanced, high-precision instruments specifically designed for the glass industry, to produce the required results.
  • Applications +

    • Batch Inlet
      Batch Inlet

      Measurement at the batch inlet provides thermal monitoring of the glass raw materials for quality control. We recommend the LWIR-640 thermal imager or RT8 thermometer for this application.
