Heating Hoses
35
Series H 300 A
Analytical heating hose with exchangeable
inner cores, which protrude at the ends
Applications:
Maintaining the temperature of probe lines for engine exhaust
gases, CO
2
measurements, industrial waste gases, blast furnace
waste gases, air measurements, etc.
The core of this heating hose continues without interruption or
restriction from the discharge point up to analysis. The heavy-gauge
conduit thread cable glands fi tted at both ends simplify assembly.
This design permits quick on-site replacement of the inner core
when inside walls are contaminated.
