Can be used with a printer (USB function optional) 13. A variety of signal combination relay outputs, and the signals can be subjected to logical operations (NOT, AND, OR, NOR, XOR), referred to as PLC programming ability 14. Diversified relay control methods: parameter->relay mode, relay->parameter mode, logic combination mode, composite signal mode 15. Program editing: 120 groups of programs can be programmed, and each group of programs can program up to 100 segments |
| Cooling system | |
| Operation mode | Air-cooled mechanical compression single-stage refrigeration mode |
| Heating and cooling devices | 1. Hitachi or Emerson low-temperature and low-noise scroll compressor (air-cooled heat dissipation method). 2. Cooling method: air cooling |
| Heat and cold exchange device | Single-stage refrigeration system, Emerson low-temperature and low-noise scroll compressor imported from the United States. Adopting ultra-high-efficiency SWEP cold coal heat and cold exchange design [made in Sweden (sus#316)], it is more efficient than the traditional internal spiral type. |
| Heating load adjustment | 1. The automatic adjustment of the cold coal flow rate device is adopted to effectively take away the heating load of the product to be tested, which is synchronized with German/Japanese technology. 2. Compared with traditional designs, the control stability and reproducibility are higher, and it achieves ultra-high performance in terms of power saving and energy saving. |
