High-performance, energy-saving, programmble constant temperature, forced convection ovens with air velocity control and exhaust dampers.

They achieve an energy-saving rate of 30 to 40% compared to previous models. Air velocity can be changed in 10 stages using the digital setting of the controller. Operability has been enhanced by locating a slider-type open/close adjustment knob on the front side of the main unit.

• Special construction makes it difficult for dust from surrounding environment to enter the oven.
• Temperature settings, measurement temperatures, over-heating prevention temperature settings are displayed simultaneously with the digital setting and display system.
• Programmable operation enables a maximum of 32 steps repeat and graduated operation.
• Calibration offsetting, timer, integrated time calculation and other added functions.
• Comprehensive safety features.
• A recorder can be equipped as option.
