Orton Glass Testing Instruments

The Orton Series of Glass Testing Instruments are designed for determining specific temperature points or specific temperature / viscosity ranges. This is ideal for glass manufacturers, researchers, or technologists that are interested in specific temperature points, such as the softening point, annealing point, strain point, liquidus point, transition temperature, and are also interested in various temperature ranges of viscosities.
