The C1900 is a fully programmable circular chart recorder/controller combining two PID control loops with 4-pen recording. Analog, heat/cool, time proportioning or on/off control can all be selected as standard. Motorized valve operation, with or without feedback, is available as an option. The instrument offers seamless integration of loop functionality to solve process problems, eliminating the need for auxiliary devices.
Specific applications can be fully met by using the full range of options available, including one to four-pen recording; flow totalization; process alarms; ramp/soak profile - giving outstanding flexibility in just one instrument.
