Connecting the Gas Lines
Consult the layout and flow diagrams in Appendix A for guidance. All work must
be performed by technicians qualified in instrument tubing.
SpectraSensors recommends using 1/4” O.D x 0.035” wall thickness, seamless
electro-polished stainless steel tubing.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
and safety precautions for the sample contents before installing
the gas lines.
