The Sample Conditioning System Type 5987-72 (SCS - HCDT) is designed to condition gaseous media for determining the hydrogen and hydrocarbon dew point in conjunction with the gas composition analyzer Hygrophil F/HCDT. The SCS - HCDT consists of various functional groups, which are custom designed and assembled for the relevant analysis task. The combination of individual components/assemblies does not result in any additional ignition hazards. The SCS - HCDT is suitable for operation in Zone 1.
