1. The core components, including the compressor (French Tecumseh) and circulating fan, are all imported brands, and the refrigerant is a healthy and environmentally friendly refrigerant;
2. The circulating fan is automatically controlled, and the wind speed can be automatically adjusted according to the temperature. The classic arrangement of the refrigeration system has been tested by the market for many years, ensuring safety and reliability;
3. Large LCD screen/7-inch touch screen (optional) microcomputer intelligent temperature control system with PID logic calculation function, enabling manual PID control and PID self-tuning functions;
4. It has a capacity of 100 programs, 1000 segments, and 999 cycle steps, with a maximum setting time of 99 hours and 59 minutes for each segment, which can meet almost any experimental procedure;
5. One screen displays setting parameters, current running program number, current running time and remaining time, heater working status, humidifier working status, remaining cycle times, etc. It can display the program running curve, freely switch between constant value control and program control, freely switch between Chinese and English, automatically detect, display, and alarm for faults;
6. Adopting the internationally popular internal humidification method, it has better temperature stability compared to external humidification. The international brand humidity sensor ensures accurate humidity to an internationally advanced level;
7. Automatic parameter saving in case of emergencies, and power-on recovery function. It also features sensor self-diagnosis, over-temperature, and fault alarm functions;
8. The inner liner is made of 304 stainless steel, and the outer shell is made of high-quality cold-rolled steel plate with electrostatic coating, ensuring a firm and durable paint finish and preventing rust;
9. Extra-large observation window with double-layer hollow tempered glass, allowing for a clear view and precise control of the experiment;
10. Magnetic sealing door, easy to open and with good sealing performance;
11. Adjustable shelves for more efficient space utilization;
12. User-friendly design, standard configuration includes internal lighting and test ports to meet various experimental needs;
13. We can provide customers with a series of services such as IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification) to ensure the performance and specifications of the pharmaceutical cabinet (fee applies);
14. Third-party metrology reports are available upon request (fee applies);
