Analytical sample gas lines with replaceable inner core and cable screw fitting
H 300 A series350 °C
Application potential: Maintaining the temperature of probe lines for motor exhaust, CO2 measurements, industrial exhaust gasses, blast furnace exhaust gasses, air testing, etc.
The core of this heating hose runs uninterrupted and unrestricted from the extraction point to the analysis unit.
Threaded cable fittings on both ends simplify assembly on housings.
This version permits quick on-site replacement of the inner core if the inside walls are contaminated.
