Low-temperature incubators, also known as low-temperature storage cabinets, are dual-temperature incubation or preservation units suitable for research institutes, electronics, chemical laboratories, hospitals, blood banks, and disease control centres. They are widely employed for storing culture media, serum, pharmaceuticals, and for microbial cultivation and environmental testing. Additionally, they serve for low-temperature testing of electronic components, resins, rubber and plastics, toys, and specialised materials.
1. Features a microprocessor-based intelligent temperature controller with self-diagnostic function upon startup and PID logic operation capability, automatically correcting temperature deviations based on computational results;
2. Equipped with a 5.7-inch LCD controller displaying three rows of digital readouts. A single screen shows constant temperature duration, operating temperature, setpoint temperature, heating status, and over-temperature alarm information, enabling real-time monitoring of experimental progress;
3. Core components—compressor and circulation fan—employ renowned domestic brands. Utilises a healthy, fluorine-free, environmentally friendly refrigerant to ensure laboratory environmental safety;
4. Circulation fan features automatic control, adjusting airflow speed according to temperature levels. The refrigeration system employs a classic arrangement and combination, with stability proven through years of market testing, ensuring safety and reliability;
5. Employs internationally favoured internal humidification, offering superior temperature stability compared to external methods; international-grade humidity sensors deliver precision matching advanced global standards;
6. Inner chamber constructed from 304 stainless steel, outer casing from premium cold-rolled steel plate with electrostatic powder coating. Durable finish provides corrosion resistance, acid resistance, easy cleaning, and permanent rust prevention;
7. Automatically monitors operational status; exceeds limit temperature, automatically cuts off heating and alerts operators via audible and visual alarms to ensure uninterrupted experimentation;
8. Double-door structure: opening the outer door allows 360-degree unobstructed observation of the chamber's experimental conditions through the inner tempered glass door, with no impact on internal temperature;
9. Automatically saves parameters during emergencies with power-restoration capability, alongside sensor self-diagnosis and alarms for over-temperature and faults;
10. Magnetic seal door for effortless opening and superior sealing; vertically adjustable shelves maximise space utilisation.
11. User-centric design includes standard interior lighting and test ports to accommodate diverse experimental requirements.
