Parr Instrument
Company offers a
full line of reac-
tor controllers to
monitor, control,
datalog and
archive test data.
The Model 4848 Modular
Controller is our general-
purpose reactor controller. It
can control temperature and
stirring speed, and it can be
equipped to monitor a redun-
dant temperature and pressure.
It can datalog and be operated
remotely from a PC.
The Model 4838 Temper-
ature Controller is offered to
control temperature in non-
stirred pressure vessels. It can
be expanded to include an
optional pressure or redundant
temperature module.
The Model 4871 Process
Controller is a full featured
process controller, which can
handle either a single reactor
with a wide variety of inputs
and outputs or multiple reac-
tors running independently.
It controls the entire process
including gas and liquid flows
through a PC interface custom
tailored to the application.
