PRODUCT FEATURES

• The system has the function of digital temperature display and temperature inside the cabinet can be set within a range from -20℃ to -40℃ The high-precision microcomputer temperature control system and platinum resistor temperature sensors ensure more precise temperature control
• Seven transparent drawers can be used for storage based on classification.
• The two-layer thermal insulating foamed door can prevent loss of refrigerating capacity in an effective way The cabinet is made from
• CFC-free polyurethane material, which can improve its heat insulating performance to a large extent
• The well-developed audible & visual alarm system makes it safer for storage
• The turn-on delay and stopping interval protection function can ensure reliability in running
• The keyboard lock function can prevent any adjustment of operating parameters without permission The door is equipped with a lock, improving security of sample storage.
