Tubular furnace 3119-160

for materials testing machines

The Instron 3119-160 is a 3 Zone Split Tube Furnace with a side entry extensometer port. It is manufactured with a wire-wound element for maximum operation up to 1200°C (2200°F). The elements are uniquely formed to provide optimum temperature uniformity, ensuring conformance with testing standards such as ASTM E21, ISO 6892-2, EN10002-5,and EN2002-2. Top and bottom furnace end plates are provided, designed to be durable and provide excellent insulation. They include a 20mm (0.787in) diameter hole for use with pull rods. To ensure operator safety the furnace uses high-grade insulation that does not use Refractory Ceramic Fiber (RCF). To prevent burns, the furnace has a protective shield which makes minimal contact with the furnace to prevent heat transfer, meaning that the external surfaces are not excessively hot during normal operation. Type K thermocouples with miniature plugs are mounted on the center line in the center of each heated zone. To prevent costly replacements of damaged thermocouples, there is a quick release connection on the outside of the furnace. Should damage occur, it is a simple replacement instead of a complex installation.
