Innovative Industrial TC RTD pid temperature controller with digital display
General Description
REX series PID Temperature Controller is the new product developed by
our company. It adopts special microcomputer adjusting meter that
employs switching power and surface mount technology (SMT), therefore,
the controller is quite smart and reliable. Its special functions like auto
diagnosing, auto setting and intelligent control. It can be used widely in the
display and control of the parameter of the temperature, pressure, flow, and
liquid level.
