The following are the main features of the new
Emerson Process Management X-STREAM
gas analyzers in brief:
• compact design with easily accessible
internal components
• customizable for a wide range of ap-
plications: different housings are avail-
able while internal construction remains
largely identical
• multilingual microprocessor-controlled
user interface with liquid crystal (LCD)
or vacuum flourescent display (VFD) to
indicate measurement value and status
messages
• units for outdoor use are optionally sup-
plied with an impact tested front panel
• widerange power supply unit for worldwi-
de use without modification (
with internal or external PSUs)
X-STREAM X2 gas analyzers can measure
up to four different gas components by mul-
tiple combinations of the following analyzing
techniques (restrictions apply to ½19in units):
IR = non-dispersive infrared analysis
UV = ultraviolet analysis
pO = paramagnetic oxygen analysis
2
eO = electrochemical oxygen analysis
2
tO2 = electrochemical trace oxygen analysis
TC = thermal conductivity analysis
tH O = trace moisture measurement

Modified resistant measuring cells are avai-
lable for use with corrosive gases and/or
gases containing solvents.
