Applications
The XTC601 binary gas analyzer is designed for use in process environments.
A sample system may be required to ensure that a clean, dry gas with no particles
or oil-mist is delivered to the XTC601. This will ensure the sensor is not damaged or
contaminated by the process. Michell Instruments is able to supply a quotation for such
a system.
Examples of applications include:

O-Ring Selection
The XTC601 has only one elastomeric seal in the gas path. There are 3 types of O-rings
available 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 version is
dependent on the lowest ambient temperature of the area the units are to be installed in:
Ambient temperature range for transport and storage:
-40°C to +60°C (-40°F to +140°F) (for Silicone O-ring)
-15°C to +60°C (+5°F to +140°F) (for Viton O-ring) – Standard
-10°C to +60°C (+14°F to +140°F) (for Ekraz O-ring)
NOTE: The silicone O-ring cannot be selected for samples containing > 21% 0
