Fast, accurate and easy to use instruments for measuring and
analyzing carbon dioxide or oxygen. Fyrite Analyzers are available
for either CO2 or O2 analysis, and each model is produced in three
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% CO2 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 CO2 fluid is good for
approximately 300 gas samples and the O2 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). Order
Fyrite Instruction Manual 11-9026. For temperatures
above 1400°F, a ceramic sampling tube (Bacharach
Part # 11-0164) is available.
- 0-7.6% CO2 – CO2 tests of controlled atmospheres in fruit, vegetable, meat storage rooms, and incubator monitoring.
- 0-7.6% O2 – Oxygen determination in flammable gases; oxygen tests
to check inertness of atmosphere in silos, fuel tanks, etc.
- 0-20% CO2 – Flue gas combustion tests; CO2 tests of heat treating
- 0-21% O2 – Flue gas combustion tests, oxygen deficiency test.
