260°C MECHANICAL CONVECTION OVENS, GENERAL PURPOSE

MO1490 Lindberg/Blue M +260°C Mechanical Convection Ovens combine positive, forced-air circulation with digital temperature control to achieve dependable, uniform conditions for a variety of laboratory applications. Advantages include faster heating of work load, closer temperature uniformity throughout the chamber, absence of radiant heat and more efficient transfer of heat from heating element. Triple-wall cabinet construction reduces external cabinet temperature and improves energy efficiency. All models are UL and CUL listed for safety and performance. CE mark on select models.

General Features
