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 can automatically adjust the wind speed 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 operation 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 time setting of 99 hours and 59 minutes for each segment, which can meet almost any experimental procedure;
5. One screen displays setting parameters, current 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. It adopts the internationally popular internal humidification method, which has better temperature stability compared to external humidification. International brand humidity sensor, providing humidity accuracy reaching internationally advanced levels;
7. Automatic parameter saving in case of emergencies, with power-on recovery function, and also features sensor self-diagnosis, over-temperature and fault alarm functions;
8. The inner chamber is made of 304 stainless steel, and the outer casing is made of high-quality cold-rolled steel plate with electrostatic coating, ensuring a durable and rust-proof finish;
9. Extra-large observation window with double-layer tempered glass, allowing for clear and precise monitoring of the experimental process;
10. Magnetic sealing door for easy opening and excellent sealing;
11. The lighting system uses LED cold light source layered lighting, with stepless adjustment of illuminance and selectable spectral range (high-intensity light drug cabinet/general drug cabinet);
12. Adjustable shelves for more efficient space utilization;
13. User-friendly design, standard with internal lighting and test ports to meet various experimental needs;
14. We can provide customers with a series of services including IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification) to ensure the performance and specifications of the drug cabinet (fee applies);
Third-party calibration reports are available for a fee.
