The 4838 Reactor Controller is designed to control the temperature in our line of non-stirred pressure vessels. No provision is made for the current or future expansion to control motor stirring speeds or to actuate cooling water.

The controller contains the same Primary Temperature Control Module used in the 4848 Controller and provides identical control and communications capabilities. A high/low heater switch feature, as well as a lockout relay and reset for over temperature protection, are also included.

Features found on the 4838 Reactor Controller are:
- PID Programming with Auto-tuning capability for precise temperature control and minimum overshoot
- Ramp and soak programming
- High or low power heater switch
- Lockout relay and reset for over temperature protection.
