The Parr 4848 Reactor Controller brings digital communications to all of the functions of these modular reactor controllers. The 4848 offers all of the features expected in a Parr general purpose reactor controller, namely:

- PID programming with Auto-tuning capability for precise temperature control and minimum overshoot
- Ramp and soak programming
- Separate heating and cooling control loops
- Optional Solenoid Valve Module for cooling control
- Motor speed control
- High or low power heater switch
- Lockout relay and reset for over temperature protection
- Optional expansion modules for tachometer, pressure, and high temperature alarm

With the 4848 Controller, all the expansion modules as well as the primary temperature control module are equipped with bidirectional digital communications [RS-485] that enable the user to not only log all current readings to a PC, but also to send set points, stirrer speeds, and alarm values from the PC to the 4848 Controller.
