Professional Technology: Digital thermostat adopts industrial-grade professional self-tuning PID technology. Compared with traditional PID control, it has the characteristics of fast temperature control, fast response, small overshoot and high precision. Self-Diagnostic Function: Self-tuning function and high-intelligence control function help operators get good results with simple operation. Self-tuning control: output, alarm and self-tuning can be indicated by LED. Powerful: This versatile controller features a special microprocessor switching power supply and SMT. Environment with no corrosive gas 30~85% RH. Professional Manufacturing: Reliable performance, powerful, easy to operate. PIN control (including ON/OFF, step-type PID and continuous PID. Process Value (PV), Setting value (SV). Widely Used: Temperature controller is mainly used in electric power, chemical, injection molding, food, incubator, oven and many other equipment.
