Our controls feature a digital dual output display for set point and process temperature indication. The automatic-tuning feature ensures increased temperature accuracy with minimum overshoot. Easy set-up and simple input commands make our controls very "user friendly". This control is a single output PID control with the capability of adjusting the AC output voltage with fixed positions and ideal for small heat loads. This control displays both the setpoint and process temperature and uses the most modern PID control technology for the best temperature stability. The Auto-tune feature minimizes setpoint overshoot and learns your process. Changing your setpoint is easily done with the interface keys. Several sensor input types are available. This unit comes with an audible alarm function, 6'. detachable power cord and grid support bracket, which is ideal for fume hood mounting to maximize bench space. This model of control can accept a type "J", "K", or "T" thermocouple, depending on the model ordered. The control automatically sets the PID parameters through a "learning" sequence in the auto tuning mode. PID parameters include proportional band, reset/integral and rate/derivative. User-friendly features include automatic LED indicators to aid in monitoring and setup, as well as dual LED displays for process temperature and set point indication. This control automatically stores all information in a non-volatile memory.
