===============================
NOTE 1: The CONTHOS-TCD utilizes the principle of thermal
conductivity. This inherently non-selective
principle is ideally suited to binary gas mixtures. For gases with multiple
components it is necessary to
consider the various gases comprising the sample, as well as dynamic
fluctuations in their concentrations.
These considerations can help to provide a basis for defining a reference
gas and the appropriate method of interference correction.
NOTE 2: The customer must ensure that the sample gas is dry and free
of particulates.
NOTE 3: Unless otherwise specified the CONTHOS gas analyzer is
neither ex-proof nor intrinsically safe in
terms of explosion protection.
The CONTHOS should not be used for measuring ignitable gas mixtures.
The customer must ensure compliance with applicable regulations when
using the analyzer with
inflammable or toxic gases or when installing within explosion
endangered environments.
