The electrically heated tube furnaces of the Hesse Instruments heating microscope are compact and functional. Different furnace models are designed for different requirements regarding maximum temperatures or heating rates. Defined furnace atmospheres can be realized with all furnace models: oxidizing, reducing or inert atmospheres as well as a moderate vacuum. Equipped with high performance molybdenum disilicide heating elements, the furnace models HT-16 and HT-19 are exceptionally long living.

The heating microscope comes with an appropriate furnace control unit built-in in the entire system. Control units feature an elaborate safety design: heating element temperature, heating current and water flow rate for the furnace closures are continuously monitored. This also contributes to the furnaces' long life.
