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.
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 atmospheres.
0-21% O2 –
Flue gas combustion tests, oxygen
deficiency test. Checking oxygen
concentrations in hydrogen cooled
generators and oil sealed inert gas
transformers.
0-60% CO2 –
Checking CO2 in inert gas blankets
in tankers and barges carrying
gasoline and other combustibles;
CO2 tests on lime kilns; checking
CO2 in sewage plant digesters.
0-60% O2 –
Oxygen test in connection with
oxygen and gas anesthesiology.
