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 ±1/2% CO
2
or 0
2
.

Operation
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.
Features
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). Order
Fyrite Instruction Manual 11-9026. For temperatures
above 1400°F, a ceramic sampling tube (Bacharach
Part # 11-0164) is available.
