Product description
The M 260 drying and heating chamber provides controlled forced-convection conditions for material testing and aging trials. With a working range up to +300 °C, reinforced fans and APT.line™ preheating technology ensure fast, uniform temperature distribution and repeatable test conditions.

Benefits

• Uniform temperature distribution using APT.line™ preheating chamber
• Consistent test conditions regardless of sample size and quantity
• Low heat loss due to effective thermal insulation
• Flexible, advanced programming and data export options

Important characteristics

• Temperature range: from +14 °C above ambient temperature up to +300 °C
• High temperature accuracy with APT.line™ technology and increased heating output
• Reinforced fan with adjustable speed; air change rate at 100 °C: 65 x/h
• Electromechanical control of exhaust air flap
• Intuitive touchscreen controller with time-segment and real-time programming; internal data logger with open-format USB readout
• 2 chrome-plated racks (std.), up to 8 racks possible; load per rack: 40 kg; permitted total load: 270 kg
• Independent adjustable temperature safety devices: Class 2 and Class 3.1 (DIN 12880) with visual/acoustic alarm option
• Failsafe backup sensor: Pt 100
• Computer interface: Ethernet
