触控智能定硫仪是依据库仑滴定法的原理（参见GB/T 214—1996）制成的。由单片机系统进行高温炉的温度控制和库仑滴定结果的测量，由液晶显示屏显示，并向单片机系统发送相应控制命令，由单片机系统独立完成相应工作。
Intelligent Touch Control Sulfur Detector is made based on the principle of coulometric titration (refer to GB/T 214-1996). The temperature in the high temperature furnace is controlled by the SCM system, and the coulometric titration result is measured by the SCM system and then shown on the LCD. After receiving the corresponding control command, the SCM system will finish the corresponding work independently.
