1. Advanced and reliable refrigeration system:
■European and American totally-enclosed compressor imported with original packing
■adopt imported environmental protection cooling media (R507, R404A or R23)
■have the refrigeration components and high efficiency cold and heat exchange system with the most famous brand in the world
■excellent process and low failure rate
2. English and Chinese LED LCD touch screen controller imported with original packing
3. large electrothermal watch window:
4. Reliable and excellent uniform air supply system
■the top of long axis motor is vertically installed to prevent the main shaft decentralization due to long-term continuous operation.
■the double deflection air supply of imported centrifugal blower can be adjusted according to horizontal and vertical angles to ensure more consistent temperature and humidity uniformity of the cabinet.
5. Stable and reliable water cycle supply system:
■the pipeline design ensures the uniformity of cabinet pressure, water pressure and external atmosphere pressure to prevent vapor leakage.
■ the key parts of water pipeline adopts the production of opening mold to prevent water blocking caused by water pipeline pollution.
6. Two different materials can be selected:
■Atomized stainless steel surface, if the cleaning is frequently made along the lines clean, the completely new appearance of the machine can be maintained,(such an option is recommended)
■Electrostatic spraying surface of high quality (according to customer requirements)
7. The equipments have specialized software which can make one computer control multi testing machine (optional)
8. High quality components and optimized design are adopted to make the lower noise of the machine operation.

 Product advantages
1. The controller operation uses the fuzzy algorithm, the latest technology control and proper adjustment of refrigeration to make the best results; 7 "TFT true color LCD touch screen is larger than the other screens.
2.The controller interface of humanization design has more convenient operation and more reliable operation.
3. The refrigeration control system adopts cooling demand algorithm to reasonably and effectively use cooling capacity and effectively reduce the mutual consumption of heat and cold so as to achieve control stability and energy saving.
4.The coupling PID adopted by the temperature and humidity control can effectively prevent the sudden run away   of the controlled humidity value, which not only makes constant temperature and humidity but also achieves well the function of alternating temperature and humidity .
5.The refrigeration system adopts imported compressor which has the lower noise and better performance.
6. The sampling calculation for a second can ensure the real-time curve sampling and historical data storage for 110 days. The sampling rate can be arbitrarily set from 3 seconds to an hour.
7. Extra long constant time of 99999 hours .
8. The program segment setting time of 540 hours and 59 minutes.
9. There is the USB interface to connect computer and corporate LAN.
