Semiconductor Temperature ControllerFeatures?-Intelligent and stepless temperature control in both directions?-High accuracy of �.1 degrees in temperature control?-Arbitrary working temperature setting(in general between -20 ? and 85 ?, other range will be custom-made);-Alarm reminding if the working temperature overstep the setting limit(set by software)-The modifiable temperature PID feedback parameters?-Either cold or thermal with homothermal mode;-Protections of over high current, voltage and heat?-Protective circuits preventing hardware from being either too hot or too cold?-high stability and anti-interference because of eliminations of the interference of power frequency(50/60Hz) in the temperature sampling channel;-Character-based LCD and membrane keyboard;-User-friendly menu interface and self-diagnosis of malfunction (when improper operation or power failure occurs, the power supply will give malfunction number hint);-The dimension: W �L �H = 450 x 130 x 320;-Custom-made accordingly.
