URC II - Universal Reactor Controller

Fully integrated control, monitoring, and data handling of temperature, pressure, stirring speed,
and other parameters for laboratory style reactors


The URC II Controller is an integrated package utilizing a Programmable Logic Controller (PLC) for all process control, monitoring and coordination in conjunction with a touch screen operator display unit. The URC II provides the operator with a concise point of control for all processes related to a reactor system. The unit controls and monitors the reactor’s external and internal temperatures, the speed of the mixture, and the pressure within the reactor.

Electrical equipment used to control any and all reactor functions. URC II (URC 2) Universal Reactor Controller
