• The PID with advanced feed-forward circuitry (2 degrees of freedom) of
the CQM1-TC20@/TC30@ assures stable temperature control. The Units
can also be set to ON/OFF control.
• Temperature Control Units are available for either 4-loop temperature con-
trol or 2-loop temperature control, and Units with 2-loop temperature con-
trol provide a heater burnout alarm. You can also select between
thermocouples or platinum resistance thermometers as the input sensors.
