Features
1. Adopt advanced measurement device, the controller adopts large-scale color liquid crystal man-machine touch conversational LCD interface controller, which is easy to operate, easy to learn, stable and reliable, and the Chinese price text displays the complete system operation status and setting program curve.
2. sets of 100 test specifications are independently set, the test time is 99999 hours and 59 minutes, and the cycle period can be set from 1 to 999 times, which can realize the automatic operation of the refrigeration unit, meet the functions of data exchange and remote control of host connection, and reduce the workload of operators .
3. There is a test hole with a diameter of 50mm in the middle part of the right side of the box, which can be used for external power supply personnel to carry and test components.
4. Fully automatic high-precision circuit temperature control system, any movement of the machine is completely locked by P.I.C, all of which are controlled by P.I.D automatic calculation, and the temperature control accuracy is high.
5. The advanced and scientific air circulation design makes the temperature in the experiment box uniform and avoids any dead angle. The complete safety protection device avoids any potential safety hazards and perfectly realizes the full temperature control.
6. When an abnormal situation occurs in the status display and curve display during operation, the fault point and cause will be automatically displayed on the screen immediately and the troubleshooting method will be provided.
7. The refrigeration system adopts the cascade high-efficiency low-temperature circuit heat exchange design, and the refrigeration unit adopts the low-noise design of imported compressors from Europe and America, and uses green environmental protection (HFC) refrigerants R404A and R23 with zero oxygen coefficient.
8. The automatic pressure relief device of the refrigeration system can effectively improve the high pressure alarm failure of the compressor caused by heat dissipation or other problems.
9. The electronic expansion valve cooperates with the quick opening valve to effectively control the cooling room of the system, reduce the output power of the heating system, and save energy.
