Chapter 5 Features and specifications
5.1 Key features
Delicate insulation with environment friendly rock wool and the unique design of ventilation
keep the surface temperature of the equipment from being burnt even when the oven is
maintained at above +200
°
C.
Silent hot-air blower and the unique design of air circulation provide uniform air movement
and improved temperature distribution, best stability ±0.1K, uniformity ±1%.
Microprocessor controlled maximum, minimum temperature and opened-door cut-off and
alarm functions protect the equipment and specimen from being over-heated, and
auto-restart capability after power failure keeps your test un-interrupted.
Hair-style polished stainless steel interior and rounded-corner interior make the daily clean
easy for corrosive-resistant long life operation. Adjustable shelves help you to make more
space for different height.
Applicable for drying, burning, sterilizing and aging in fields of medicals and pharmaceuticals,
life science, agriculture and food industries, and electric and electronic industries.
