1. Working conditions: ambient temperature 10～32℃, working environment humidity: 20-80%, power supply 380V±10%, 50Hz±1HZ. 2. Style: horizontal. *3. Display: LED digital temperature display, real-time display of box temperature and various set parameters (temperature, voltage, ambient temperature, compressor operating status, etc.), the operating status is clear at a glance. *4. Temperature control: high-precision microcomputer temperature control system, the temperature in the box can be set arbitrarily in the range of -120℃～-164℃, and the operation is stable. 5. Cabinet material: high-quality structural steel plate, advanced anti-corrosion phosphating spraying process. *6. Liner material: stainless steel liner, corrosion-resistant, long service life, and easy to clean. *7. Insulation material: thick insulation layer and VIP insulation board, multi-door seal design, good insulation effect. *8. The non-fluorine environmentally friendly refrigerant invented by the Institute of Physics and Chemistry of the Chinese Academy of Sciences has a unique refrigeration circuit with independent intellectual property rights, which has a faster refrigeration speed and a more uniform temperature. Single-stage lubricating oil compressor refrigeration technology, with stronger refrigeration capacity. *9. Safe storage: complete sound and light alarm system (high and low temperature, door opening, abnormal voltage, power failure alarm, sensor failure, condenser heat dissipation, system failure, etc.), and the storage of items is safer; 10. Power-on delay and shutdown interval protection functions to ensure reliable operation; keyboard lock and password protection functions to prevent arbitrary adjustment of operating parameters; *11. Imported high-efficiency compressor, strong power, more reliable quality, imported EBM low-noise fan, high-efficiency and energy-saving. The condensing fan and compressor cooling fan can be started and stopped intelligently according to changes in ambient temperature and the operating status of the compressor. 12. The test hole design is convenient to test the temperature in the box. *13. The standard temperature record printer can read the temperature data at any time. Optional remote communication centralized monitoring system, liquid nitrogen/carbon dioxide backup system.
