The standard brick lined bench mounting electrically operated type TG9 or TG9FW version (with an increased chamber width), both have a maximum operating temperature of 1300 °C. A muffled chamber protects graded heating elements that provide a temperature differential over 9 points of around 180 °C i.e. approximately 20 / 25 °C between each temperature reference point.
A total of nine thermocouples are located 50 mm apart with variable height adjustment to suit test piece sizes. The temperature of the samples can be checked at any time during the firing on the programme controller.
The TG9F and TG9FW share the same high specification.
