System Options and Accessories
The standard THJ80 comes equipped with a holding arm and pneumatic lift to support the air
delivery assembly, and automatically raise or lower the shroud. The no-arm option comes
with a cradle to hold the nozzle when the arm assembly is not required. See page 18 for
instructions on operation of the motorized arm option.
The system PLC controls all aspects of the temperature testing. FTS designed the control
algorithms and features specifically for the THJ80 to provide an easy-to-learn, user-friendly
operating environment through the touch screen while still providing the flexibility of remote
access and data logging.
