Contaminated Refrigerants
The
YELLOW JACKET 68940
includes the ability to detect and analyze the composition of
many common R400 Series refrigerants in addition to
R22, R32, R134a
and
Hydrocarbons
(HC)
. In the event that the
YELLOW JACKET 68940
determines that the primary refrigerant
in the system or cylinder is one of the measured refrigerants, the results will display as follows
in
(Figure 11)
.
Pressing the ‘MORE’ button will display the detail screen shown in
(Figure
12).
If the blend or refrigerant mixture is not recognized, the screen shown in
(Figure 13)
will
be displayed. Refer to section
2.10 Print the Test Results & Channel Data
to print.
2.8
Pure Refrigerants
The
YELLOW JACKET 68940
has the ability to
identify
the following refrigerants:
R12,
R1234yf, R408A, R409A, R417A, R421A, R421B, R422A, R422B, R422C, R427A and
Hydrocarbons (HC).
All
identified
refrigerants will displa
y with “Purity Unknown” as the
analyzer cannot yield additional information regarding the composition
(Figure 14)
. Refer to
2.12 Channel Data Modelling
for additional information regarding
identified
Refrigerants.
The instrument can also,
Identify and Analyze
the component content of pure
R134a, R22,
HC (Hydrocarbons), R404A, R407C and R410A.
Analysis of analyzed pure blend
refrigerants will yield additional data regarding the composition of the refrigerant sample. The
YELLOW JACKET 68940
will display the blend refrigerant type as shown in
(Figure 15)
.
Pressing the ‘MORE’ button will display the detail screen shown in
(Figure 16).
Refer to
section
2.10 Print the Test Results & Channel Data
to print.
NOTE:
Hydrocarbons (HC) encompass
R600, R600A and R290
and this machine cannot
differentiate between Hydrocarbons.
