Upright Ultra-Low Temperature Freezer, Precise 0.1°C Control, Multiple Alarm Protection System, for Research Low-Temp Tests 28L-108L, -25°C~-86°C (58L -40°C)

Four Major Advantages: No.1 Comprehensive Protection System Features multiple protections including buzzer and flashing light alarms (password protection, frequent start protection, and system continues cooling in case of sensor failure). No.2 Refrigeration and Insulation System Uses a compressor with a fluorine-free environmentally friendly mixed refrigerant. The single compressor system has a low failure rate and low energy consumption. The silent fan offers stable performance and low noise. No.3 Intelligent Temperature Control Microcomputer digital control, digital temperature display, adjustable in 0.1 degree Celsius increments. The internal temperature is adjustable, and the start/stop temperature difference can be set. It has high and low temperature alarms and can be freely configured. No.4 User-Friendly Design Wide voltage design, suitable for use under 187V-242VAC voltage. Customizable test port function, balanced chamber air pressure, and convenient temperature testing. High-quality materials are used throughout the design.
