INTRODUCTION
1.2 Applications
The XTP601 has a robust sensor with high sensitivity and stability. It can be factory-
calibrated in varying backgrounds to match the customer’s process gas. The analyzer
has a built-in local user interface with a display. The capacitive buttons work through
the glass face, without needing to remove the lid.
Together with the purpose designed sampling system, the XTP601 is able to work under
various process and environmental conditions. Examples of applications include:
• Monitoring inert blanketing gases
• Oxygen measurement at inlet of compressors in steel or gas industries
for safety
• Biogas, waste, landfill and digester plants
• Inert gas for pharmaceutical industry and painting gas
• Catalyst regeneration
1.3 O-Ring Selection
The XTP601 is available with 3 types of O-rings to offer greater flexibility with material
compatibility. The Viton O-ring is fitted as standard. The EKRAZ O-ring is available for
solvent resistance. For extremely low temperatures there is a closed cell Silicone O-ring.
To comply with Hazardous Area certification, the material used in the EX1 & EX3 versions
is dependent on the lowest ambient temperature of the area the units are to be installed
in:
Ambient operating range:
-40°C to +55°C (-40°F to +131°F) (for Silicone version)
-15°C to +55°C (5°F to +131°F) (for Viton version) - Standard
-10°C to +55°C (14°F to +131°F) (for Ekraz version)
NOTE: Silicone O-ring is not suitable for oxygen enriched samples,
i.e. 0
