⑩ The entire series is equipped with high-performance silent universal wheels, combining flexible movement and stable parking, suitable for precision laboratories and high-end industrial environments, showcasing detailed technology and user-friendly design.
① Color LCD Screen Controller: Equipped with a color screen and touch buttons, displaying parameters such as set temperature, operating temperature, constant temperature time, and fault information on a single screen; features dynamic PID parameter adjustment for fast response speed and temperature overshoot suppression;
② Multiple Timing Modes: 1. Timing units can be freely switched between minutes and hours; 2. Two timing modes: timing from power-on and timing after reaching constant temperature;
③ Upgraded sound and light alarm environmental scanning microcomputer chip with stable data processing capabilities;
④ Features include over-temperature alarm, over-temperature heating cut-off, timed shutdown, power-on recovery, parameter memory, temperature correction, and auto-tuning;
⑤ Power Failure Recovery Function: After a sudden power outage and subsequent power restoration, the device can automatically resume operation according to the original settings;
⑥ Auto-tuning: When the temperature control accuracy is affected by changes in ambient temperature, auto-tuning can be performed to improve temperature accuracy;
⑦ Multiple Modes: Switching between fixed-value mode and timed mode.
