Up to 1200°C Three-Zone Split Furnaces

Series: HTO 15 & 27 & 38 & 34 & 39

These three-zone split high temperature resistance furnaces are designed for materials testing in air. The double-walled design reduces the outer wall temperature through convective-cooling. This furnace is well suited for high temperature tension, compression, cyclic fatigue testing and fracture mechanics testing. The Version 15 provides 300 mm heated zone length whereas version 38 is with extended heating zone length of 360 mm and version 27 is with heated zone length of 200 mm optimized for Low Cycle Fatigue (LCF) applications in combination with high temperature LCF Grips Series HTG.

The furnace work with low voltage and high current archived by an transformer. The lower voltage on the heating elements extends the life-time of the furnace system considerable compared with those working with high voltage.

Key Features
