4838 Temperature Controller

4838 Temperature Controller (shown with HTM)

The model 4838 Temperature Controller is offered to control the temperature in non-stirred pressure vessels. It can be expanded to include an optional pressure or redundant temperature module.  This compact controller is adequate for most non-stirred applications involving heating or pressure display, but for more complex applications the 4848 Reactor Controller and 4871 Process Controller are offered.
