Combustion & Environmental Analyzers
Fyrite
®
Gas Analyzers
Fast, accurate and easy to use instruments for measuring and analyzing carbon dioxide
or oxygen. Fyrite
®
Analyzers are available for either CO
2
or O
2
analysis, and each model
is produced in three scale ranges.
All six instruments are similar in appearance and size, but differ in important
construction details, as well as in the absorbing fluids.
Each model, therefore, is suitable only for the particular gas
analysis or scale range for which it has been manufactured.
Accuracy is within ±0.5% CO
2
or 0
2
.

Fyrite
®
absorbing fluid is selective in the chemical absorption
of carbon dioxide or oxygen, respectively. Therefore, the
Fyrite
®
’s accuracy, which is well within the range required
for industrial and professional applications, does not
depend upon complicated sequential test procedures.
In addition, Fyrite
®
readings are unaffected by the presence
of most background gases in the sample.
The number of tests possible with one fluid charge
depends on the concentration of samples being tested. At
midpoint scale reading the CO
2
fluid is good for
approximately 300 gas samples and the O
2
fluid for 100
tests. The need to replace fluid can be easily determined
with a simple test, and replacement is an easy procedure.
These test procedures, as well as other good information,
are provided in the Fyrite
®
manual 11-9026

Fyrite

Indicators have a broad range; they may be
exposed to ambient temperatures from -30° to 150°F, and
gases up to 850°F may be tested with standard aspirator
sampling equipment (special sampling equipment for
higher gas temperatures or dry gases is available). See
Fyrite
®
Instruction manual 11-9026. For temperatures
above 1400°F, a ceramic sampling tube (Bacharach
®
Part
No. 11-0164) is available.
