GENERAL
The heated hose series JH3F has especially been developped for the gas analysis technology. The flexible heated hose transports the sample gas from the sampling point to the sample gas conditioning unit. The heated JH3F keeps the temperature of the sample gas above the water and acid dew point and therefore avoids condensation and ensures that none of the gas components is discharged or lost. The heated hose is available in different constructions and manufactured according to customer's specifications.
