Low and high precision low temperature microcomputer intelligent control system of the constant temperature trough has overtemperature protection, abnormal temperature sensor protection function, ensure the safety of the test touch-key operation can be accurately set temperature quickly, easy to operate.
Low microcomputer system convenient correction shows that the error of the temperature and the actual temperature, temperature correction resolution up to 0.01 ℃, the digital display temperature accurately.
Low special user can reset the PID parameters, and with the PID self-tuning function.
Low efficient closed compressor refrigeration, cooling speed.Refrigeration system with overheated, over-current multiple protection, etc.
Accurate temperature control, fast constant working temperature groove.The advanced inner loop system, inner loop for uniform temperature constant. Optional RS232 or RS485 communication interface, with a PC or PLC machine PC data transfer, such as remote control.
Low vertical horizontal two optional DCW series is horizontal, facilitate in work station.
