Product introduction



DK2200 series PID controllers include DK2204, DK2206, DK2216, DK2208, DK22H8, DK22DN. They are single loop process controllers and display instruments based on advanced microprocessor technology. They can control and display process parameters such as temperature, pressure, flow, etc. The instruments are flexible in setting, convenient in configuration and simple in operation.
