The Reactor Master Basic system automates jacketed reactor systems from other manufacturers and logs data without the need for PC software. Circulators (e.g. Julabo, Huber, Haake, Lauda etc.) stirrers (e.g. Heidolph, IKA, Chemglass etc.), thermocouples and RTDs from virtually any manufacturer can be controlled by the twist and click knob.  Data can be viewed in real time and downloaded to a USB memory stick as a .csv file. By connecting the circulator, overhead stirrer and thermocouple to the Reactor Master Basic, circulator temperature and stirrer speed can be set by the twist and click knob and displayed on the LCD screen. It is also possible to set stirring and profiles to run in a totally automated fashion. A Reactor Master Basic System contains:
