The temperature controller is an integrated intelligent temperature control instrument for regulating and controlling. It adopts a fully digital integrated design, with temperature curve programmable or fixed-point constant temperature control, multiple PID adjustments, output power limiting curve programming, manual/automatic switching, soft start, alarm Switch output, real-time data query, communication with computer and other functions, the digital display temperature meter and ZK thyristor voltage regulator are combined into one, integrating temperature measurement, adjustment, and driving. The meter directly outputs the thyristor trigger signal, which can drive each Thyristor-like load.
