1.5.7 Equipped with a microcomputer controller with an LCD screen and a high-precision temperature sensor, it monitors the temperature and humidity inside the chamber in real time, precisely adjusting the cooling/heating/humidification/dehumidification systems to ensure the accuracy and stability of temperature and humidity control.
2. The controller has a power-on self-test function and PID logic calculation function. It can automatically correct temperature and humidity deviations based on the calculation results. The large screen displays set temperature and humidity parameters, actual temperature and humidity values, running time, working status, over-temperature alarms, and other information, allowing real-time monitoring of the experiment process;
3. Multiple timing modes are available, including power-on timing, constant temperature timing, and long-term operation. Users can choose between forward or countdown timing, with timing units freely switchable between minutes and hours;
4. The core components, including the compressor and circulating fan, are from well-known brands, ensuring fast cooling speed, low energy consumption, and stable operation. The refrigerant is a healthy, fluorine-free, environmentally friendly refrigerant, reducing environmental pollution and complying with international environmental standards, guaranteeing laboratory safety;
5. Adopting an internationally popular internal humidification method, the humidification device is integrated inside the equipment, allowing for more precise humidity control and reducing the influence of the external environment on humidity. This provides users with a more stable and accurate humidity control solution, suitable for various applications with strict temperature and humidity requirements;
6. The circulating fan is automatically controlled, adjusting the wind speed according to the temperature; ensuring uniform temperature distribution inside the chamber and avoiding localized overheating or undercooling; the reasonable shelf design facilitates item classification and storage, while also promoting air circulation;
7. The cabinet uses high-efficiency insulation materials such as polyurethane foam, with a low thermal conductivity, effectively reducing heat exchange and maintaining a low-temperature environment inside the chamber. It is equipped with a double-layer sealed door to further reduce cold air leakage and improve insulation performance;
8. The system automatically tracks the operating status. When the temperature and humidity exceed the set safety range, the equipment will automatically trigger an alarm and cut off heating. Audible and visual alarms alert experiment operators to prevent equipment damage, experimental failure, or safety hazards caused by excessive temperature; it also features fault alarms and experiment completion alarms;
9. When the equipment encounters unexpected situations (such as power failure, system failure, etc.), the system will automatically save the current operating parameters (such as set temperature and humidity values, operating mode, etc.), ensuring that the equipment can resume operation after power is restored or the system restarts. 9. Quickly restores to the previous operating state, avoiding the need for resetting and adjustments due to parameter loss, and reducing downtime;
10. Uses low-noise compressors and fans, with a low-noise design to minimize noise pollution and meet the needs of various quiet environments, suitable for laboratories, hospitals, libraries, and other quiet settings;
11. The inner liner is made of 304 stainless steel, and the outer casing is made of high-quality cold-rolled steel plate with electrostatic powder coating, resulting in a durable and long-lasting finish with corrosion resistance, acid resistance, easy cleaning, and rust resistance;
12. Large capacity and flexible space configuration, with multiple specifications available to meet the needs of different users; adjustable shelves facilitate the storage of items of different sizes, improving space utilization;
13. The door seal adopts a magnetic sealing design, allowing the door to automatically align and fit tightly when closed, ensuring a good sealing effect and preventing external factors such as air, dust, and moisture from entering, guaranteeing that the internal temperature, humidity, and cleanliness are not affected by external factors;
14. Built-in data logger can record temperature change history for easy traceability and analysis (requires the addition of an export interface), and various communication interfaces such as RS232, RS482, and USB are optional, supporting remote monitoring functions, allowing users to view the temperature and operating status inside the chamber in real time via mobile phone or computer (optional).
15. Provides customized services, designing and manufacturing various special sizes or functions of constant temperature and humidity equipment according to user needs.
16. Comprehensive after-sales service, providing a 1-hour response, a 2-hour solution, and a 24-hour on-site service commitment to ensure that users have no worries.
