Intelligent digital temperature regulator adopt the advanced microcomputer intelligent control technology, and it has strong noise proofability. The products are made according to the international standards by taking wide range switching power. The products own the advanced PID adjustment composed with the latest fuzzy control to deal with the controlled high-speed changing and retardation time. Because of the advantage non-super adjusting plan, the products are easier to use. This series of intelligent digital temperature controller is an economical meter with high ration of quality to price, and can take the place of conventional digital temperature controller. It has a combined control instrument of multi-function control, alarm, transmitting as well as PID control function.
