TIP!
The standard extension tube length (position 6) is 70 mm.
Upon request, 120 mm can be ordered (when ordering specify in plain text).
The extension tube length adds up to the chosen insertion length.
For the calculation of the heat input a temperature-dependent calculation basis is available
for 70 mm and 120 mm extension tube lengths. See Chapter 1.7 "Heat input through protec-
tion tube / protection tube fitting", page 13.
