Cress’ benchtop furnaces are designed for heat-treating metal, assaying and a variety of testing in shops, laboratories and factories requiring temperatures ranging from 300 to 2,250°F. A 2,400°F maximum-temperature option also is available.

 

The furnaces feature auto-tuning, microprocessor-based controllers. Alloy-wire heating elements are coiled and mounted on the side walls in easy-to-change porcelain plates, the company says. The furnace case is constructed of heavy-gauge sheet steel, while the walls and door are made of insulating fire brick and  1,800°F block insulation. The furnaces also are equipped with dual door-safety switches—when the door is opened, power is disconnected from the heating elements.
