To make a test with the FYRITE, the metal Sampling Tube at one end of Sampling

Assembly Hose is inserted into the gas to be analyzed. The rubber Connector Plug at

the other end of the Rubber Hose is then

rmly pressed down on the spring-loaded

Valve of the instrument (See Figure 12). This simultaneously opens a passage into the

Top Reservoir and seals off the center bore.

Next, a sample of the gas is pumped into the Top Reservoir by squeezing the rub-

ber Aspirator Bulb. At least 18 bulb squeezes are required to assure that the rubber

Sampling Hose and the Top Reservoir of the FYRITE are thoroughly purged of the

previously analyzed sample. During the 18th Aspirator Bulb squeeze and immediately

before releasing Bulb, the

nger is lifted from the Connector Plug, which automati-

cally returns the Plunger Valve to upper position against its top seat.

Refer to Figure 13. With the Valve in this position, the

nal 60 cc of the gas sample is

locked into the FYRITE and the Top Reservoir is opened to the center bore so that the

gas sample can pass to the absorbing

uid. The FYRITE is then inverted, forcing the

gas sample to bubble through the absorbing solution which absorbs either CO

or O

depending on the type FYRITE in use.

Refer to Figure 14. The instrument is then turned and held upright. Absorption of the

or O

by the absorbing

uid creates a suction, which causes the Diaphragm at the

bottom to

ex upward permitting the level of the absorbing

uid to rise in the center

tube an amount proportional to the gas absorbed. The scale indication correspond-

ing to the top of the

uid column is then read as a percentage of gas absorbed by the

FYRITE

uid.

5.0 APPLICATION INFORMATION

FYRITE Analyzers are available for either Carbon Dioxide or Oxygen analysis, and

each of these models is made in the three scale ranges shown in Section 5.3. All six

instruments are similar in appearance and size, but they differ in important construc-

tion details, as well as in absorbing

uids.

5.1 FYRITE Absorbing Fluid

FYRITE absorbing

uid is selective in the chemical absorption of carbon dioxide or ox-

ygen respectively. Therefore, the FYRITE’s accuracy is well within the range required

for industrial and professional applications, and does not depend upon complicated

sequential test procedures. Further more, the FYRITE readings are unaffected by the

presence of most back ground gases in the sample.

The appearance of a dark red

uid

oating on top of CO

FYRITE solu tion is entirely

normal. The darker

uid consists of a small amount of material added to prevent

excessive foaming at the meniscus and improves readability.

5.1.1 FYRITE Refi ll Fluid (Storage Life, etc.)

FYRITE re

ll bottles should be stored at room temperature (70° F [21° C]) in the car-

ton provided, and placed in use within one year.

NOTE:

Before opening re

ll bottle, read the label and make

certain to observe all precautions.
