Fiber Optic Infrared Thermometer Raytek Marathon FA1G Series

Marathon FA1G

The Marathon FA1G is a Fiber Optic Infrared Thermometer specifically designed for measuring glass temperature from 750 to 1675°C (1382 to 3047°F). With applications ranging from measuring the molten glass in the forehearth to measuring the packing material temperature for optimum regenerator airflow control, the Marathon FA1G is designed to meet the needs of the Glass Industry. This model permits measurement of melter, refiner, regenerator, and forehearth temperatures otherwise inaccessible with non fiber optic thermometers.
