10.2.4 Air Cooling System
The Air Cooling System can not be combined with LTH heads!
The sensing head can operate in ambient temperatures up to 200°C (392°F) with the air-cooling
system. The air-cooling system comes with a T-adapter including 0.8 m / 31.5 in (optional: 2.8 m / 110
in) air hose and insulation. The T-adapter allows the air-cooling hose to be installed without
interrupting the connections to the box.
The air-cooling jacket may be combined with the right angle mirror.
